Lincoln successfully wins a ride in a limo, but the high life experience begins to change him.
Lincoln has won a limo ride for eating his weight in fancy mustard, and his sisters are excited to ride with him. However, Lori claims that Lincoln should have fun with the limo himself, and he promises them that he'll pick them up to take them to the Burpin' Burger at 5:00 P.M. As Lincoln goes around town, he encounters another limo containing Lord Tetherby, heir to the tetherball fortune, who believes that Lincoln is another heir and befriends him.
Lincoln and Tetherby go around partaking in various activities with their limos. When 5:00 nears, Lincoln wants to pick up his sisters to take them to the Burpin' Burger but Tetherby advises him not to, saying that it's "not what people who own limos do". As Lincoln continues to have fun with Tetherby, his sisters angrily wait for three hours before Lincoln comes home. When they confront him, Lincoln rudely gives them the brush-off, saying that Tetherby has invited him to a party in his honor where he will be welcomed into an exclusive club of limo owners.
On the way there, the limo gets stuck in traffic, and Lincoln horribly mistreats his chauffeur, Kirby. Suddenly, Lincoln's designated rental time expires, and Kirby kicks him out onto the highway. As he tries to get to Tetherby's mansion on foot, Lincoln gets attacked in an alley by stray dogs, gets his clothes torn, and gets hit with mud by a passing car. When he finally arrives at the party, Tetherby dumps him because he doesn't have a limo anymore, and has security kick him out of the gate, and into a trash can.
Feeling guilty about his past behavior, Lincoln apologizes to Kirby, who agrees to let Lincoln ride in the limo for another day. Lincoln also apologizes to his sisters for how he treated them, and invites them to go to the Burpin' Burger with him, which they accept. After going through the drive-thru and picking up the food, Lincoln runs into Tetherby again who invites him back to his exclusive club without his sisters now that he has the limo again, but Lincoln, not wanting anything more to do with him, refuses the offer, and he and his sisters spray him with mustard. As they drive off, they sing the Burpin' Burger jingle one last time to end the episode.
Lord Tetherby popping the balloons that look like Lincoln is a visual representation of the phrase "bursting your bubble".
Karma: Lincoln mistreated others for being poor so he got mistreated for being poor. Same thing happened to Tetherby.
Moral: Don't look down on others, respect everyone equally.
Out on a Limo - The episode title is a reference to the phrase "Out on a limb".
Grey Poupon - The multiple references connecting fancy mustard to limousines and other stereotypically "wealthy" pursuits pay homage to a popular series of 1980s commercials for the mustard depicting tuxedo-clad, English-accented gentlemen in limousines enjoying "life's finer pleasures" with the tagline "Pardon me, but do you have any Grey Poupon?"
