When Lincoln and Clyde think that Bobby is cheating on Lori, they follow him around town, gathering evidence.
Lincoln and Clyde are playing video games at the latter's house, when he tells the former about "The 20/20 Rule", so that their eyes aren't constantly looking at the screen. However when they look out the window, they notice Bobby, and Clyde immediately thinks that Bobby is cheating on her, when they see him go into another girl's house. After Bobby leaves, they go across the street, and ask him what he was doing, but Bobby tells them to not tell Lori he was there, stating it's complicated, and rides off.
Lincoln plans to tell Lori, but when he sees her, she looks so happy talking to Bobby, that he can't bring himself to tell her about what he and Clyde saw. Clyde calls him on the walkie-talkie, but Lincoln says that he couldn't bring himself to do it. Clyde mentions how he feels about Bobby, and the rest of the sisters barge into Lincoln's room, with Lola demanding that Lincoln tell them about Bobby cheating on Lori. After Lincoln explains everything that him and Clyde saw, Lisa points out that while what the boys saw and heard suggests that Bobby's cheating on Lori, they don't have enough evidence to prove Bobby's alleged unfaithfulness. Lana agrees to this, pointing out that a person has to be "a zillion percent sure" of something before telling Lori about it, because she will get furious if she's presented with false information. Lynn vouches by revealing that one time, after she once told Lori that they were out of bread but later discovered that there was still a loaf left in the house, Lori beat Lynn with said loaf.
Sometime later, the sisters (minus Lori) are with Lincoln at Clyde's house, as they stake out to get more info on Bobby. Luna announces to the others when Bobby shows up, and they listen in through a radio link, and notice them seemingly kissing through the curtains. When they exit the house, however, it turns out that the guy kissing Clyde's neighbor was a different person (presumably her actual boyfriend), while Bobby's apparently just friends with the couple. The sisters conclude that Bobby's not cheating on Lori, and get upset at Lincoln for apparently wasting their time (despite them coming up with the stakeout in the first place).
Later, Lincoln and Clyde are at the mall playing in the arcade, when Clyde brings up the 20/20 rule again. They look away, only to see Bobby in another store, and with another girl. They once again suspect Bobby of being a cheater, just with a different girl, and proceed to try and get photographic evidence before telling Lincoln's sisters again. They follow Bobby around, and see him get into another girl's car, and they proceed to try and get proof that Bobby's cheating. They arrive at a hill, where they take a picture of Bobby and the other girl in the car, and they drive off. Lincoln and Clyde continue to pursue them, eventually Bobby gets dropped off, and they follow him to yet another girl's house. They use the girl's dog to get a camera into the house, and Bobby begins to remove some of his clothing, as this only strengthens their suspicions. They follow Bobby to a café, and they notice him doing a tango with random man. They once again see him with the girl from the mall, and they see them in a jewelry store, and Bobby makes a pose with a little jewelry box, that makes it seem like he's proposing to the girl. They now feel they have enough evidence to prove that Bobby is indeed cheating on Lori, and go to tell the sisters (minus Lori). They feel bad for Lori, as she is ecstatic for her and Bobby's date that night.
They go to tell Lori, but she's already gone, and they can't contact her cellphone, so Lincoln decides that they need to head over to the restaurant to confront Bobby themselves. They arrive at the restaurant, and question Bobby about proposing to that other girl. Clyde attempts to attack Bobby, but he falls back, and lands against a bunch of food, causing it to fall over on the floor. Lori arrives, and is surprised to see her siblings at the restaurant, and Lincoln tells her that Bobby has been cheating on her, which surprises both Lori and Bobby.
Lincoln presents all of the evidence that they gathered to prove Bobby's cheating on her, but Bobby disproves all of their suspicions. He mentions that the girl from the mall, Dana, is his co-worker from the department store, and explains that she assisted him with the dress and earrings that he purchased Lori for their date. The girl whom he drove around with is a girl named Monica (whom he knows from his tour guide job), and explains that she was helping him out by showing him romantic locations that Bobby can bring Lori to. He says that the older woman whose house he visited, Pam, was fitting him for a tuxedo, and that the man from the café is named Darin, whom Bobby met on the bus, and that he was instructing Bobby on how to dance. Finally, he explains that the first girl, Teri, is his co-worker from the pizzeria, and that she was teaching him how to order food in Italian Mandarin.
Lincoln, the sisters, and Clyde feel bad for thinking that Bobby was cheating on Lori, and assume that Lori will be (understandably) furious for nearly ruining her date with Bobby. However, Lori admits that while she is kind of mad about what her siblings and Clyde did, she acknowledges that they were just trying to look out for her, and is willing to forgive them for it. Everything seems fine until Giovanni mentions how Clyde destroyed the food they had on the cart, and that they need to pay him back for it. Lori and Bobby enjoy their date while Lincoln and Clyde (and presumably the other sisters) work in the kitchen to pay back the owner. He orders the boys to make Kung Pao anchovies, and when they do open one of the cans, the smell and sliminess inside gross them out.
This episode reveals that Clyde is prohibited from watching R-rated films.
This is the third appearance of Howard and Harold's tandem bicycle, after "Hand-Me-Downer" and "Butterfly Effect".
Despite the fact that the stakeout takes place at the McBride house, Howard and Harold are never physically seen in this episode.
The music that plays during the montage of Lincoln and Clyde spying on Bobby is the same as the title card music for "Get the Message".
When Leni attempts to call Lori, her name is spelled incorrectly on her phone (it was spelled as "LOR-E").
This is one of the few episodes where Luan appears, but does not make a pun when she speaks.
This episode takes place on a Tuesday, and a Friday, since Bobby says that he's counting every minute for the date on Friday, 4,320 minutes, which is 72 hours. Lincoln and Clyde spy on him on the same day of their date.
There are 1,440 minutes in a day, so Lori and Bobby were exactly three days away from their anniversary date.
When Lori and Bobby are dancing Tango, and they do the spin, the positions they're in are reversed, with Lori being in the position that the man is usually in, and vice versa.
One of the patrons in the bistro has a hairstyle similar to Lori's, but her hair is black.
This episode reveals that Lori will get upset at whoever tells her false information. According to Lynn, one time, she claimed that there was no more bread left, but when Lori found a loaf of bread, she beat up Lynn with said loaf.
Humorously, later in the episode, when Lori says she is furious for everyone's suspicions, Lynn hides the breadsticks just in case Lori were to beat them up with them.
It wasn't clear whether Pam's dog was male or female, since Lincoln calls the dog a "good boy" and Bobby calls the dog a "pretty girl".
It's revealed that Bobby used to work at a department store, as well as a tour guide, and at a dry cleaners.
This is the last episode produced in 2016.
This episode shows that Clyde can get nauseous from shaky footage.
While Lincoln and Clyde are making "Kung Pao anchovies", the can they open reads "鳀鱼", which is Chinese for "anchovy".
When Lincoln and Clyde were viewing the footage from the dog, Bobby is seen taking off his pants, and Clyde quickly shielded his eyes. The way this scene plays out is that Clyde was given the implication that he was watching an erotic film.
In addition, Pam's line "Why don't you slip out of those clothes, and we'll get started" implies that something inappropriate will occur.
Lincoln and Clyde watch as Bobby goes with different girls, then with an older woman, with a dog, and then with a man; thus implying that they wrongly assumed Bobby was a gerontophile (sexual preference for the elderly), a zoophile (sexual preference for animals), and a homosexual (sexual preference for the same gender).
Cars - The scene where Clyde falls on to a food cart with Linguine Dim-Sum and a chef complaining about it is similar to a scene in this movie, where Lightning McQueen crashes into Luigi's tires, and Luigi complains about them being scattered.
The Golden Girls - The scene when Bobby is dancing with Darin is a reference to a scene of "The Golden Girls"
Davey and Goliath - This episode is similar to the episode, "The Shoe Maker", where Davey thought a brand new shoe maker named Pierre, who moved from France with his wife Marie, was saying bad stuff when he was speaking French and rumored to his family and friends that he's mean.
Thomas the Tank Engine & Friends - This is also similar to the season five episode, "Thomas and the Rumors where Henry, Gordon, and Percy think of what Harold is up too. This also resembles the season 9 episode, "Thomas and the New Engine" where Thomas thinks a new engine named Neville is friends with the diesel engines when he saw Neville with 'Arry and Bert, but was later wrong in the end after rescuing Neville from falling off a bridge that was under repair.
Mr. Peabody's Apples - This shares a similar plot with this book by Madonna where a kid named Tommy Tittlebottom thought an owner of a baseball was stealing apples from a market.
Possible: Lori was seen with an extra pair of eyelashes when she was tango dancing with Bobby.
When Lincoln shows the pictures to Bobby, there is one where Bobby's with Dana in the dress shop, which is impossible, since Lincoln and Clyde didn't start taking photos until after that.
When Bobby and Dana are at the dress shop, there's a moment where her eyelashes are disconnected from her eyes.
When the dog approached Bobby, he was kissing the camera rather than the dog, so it's strange he didn't notice the camera.
When Luna confronts Bobby about which of the people he was supposedly cheating with he brought to the restaurant, she says "the blonde, the guy, the dog?". However, none of the girls that Bobby cheated with is blonde. It's possible she was referring to Monica, but her hair is red, not blonde.
At the end of the episode, after Bobby explains, Clyde says he was wrong about the dog. Before this scene, Clyde was nowhere to be seen.
At times, the bell on Clyde's tandem bike is missing.
Normally Clyde's house doesn't have a bush right next to the door, like it was shown when Lincoln, Clyde, and the sisters (sans Lori) were spying on Bobby.
On CC the cc said Clyde that he said hope was replace hope with e.
In the credits, Lisa is said to be voiced by Lara Jill Miller, AND Grey Griffin.
In addition, Lola's name isn't there.
