"Intern for the Worse" is the fifty-fourth episode of The Loud House.
It's the annual Internship Fair at school today. Lincoln and Clyde are attending the Job Fair because they have one place in mind they want to work at: Flip's Food & Fuel. The two ask Flip if they can work at his gas station and he immediately hires them, on account that they don't have any criminal records so they briefly celebrate before being told by Flip to get to work.
At Flip's Food and Fuel, Flip instructs the boys on how to handle some simple tasks, such as cleaning a customer's windshield and changing the expiring date on cartons of milk but when the two are ready to get to work, Flip gives off an extra incentive: whoever does the best job will be promoted to manager, and that they'll get possession of the unlimited Flippee cup, a cup that allows the possessor to have as many Flippees as they want. Almost immediately, the two begin to work hard in hopes of making a good impression.
Lana and Lola drive up to the gas station, and Lincoln and Clyde immediately greet them. Lola has to use the bathroom, while Lana requests that the car be filled up. Lincoln starts filling up the car and gives Lana a bag of beef jerky, making Clyde envious. When Clyde learns that Lola can't use the bathroom due to its revolting status, Clyde gets to work making the bathroom tidy. Lola then exits the bathroom satisfied and the two part off, telling the boys to keep up the good work.
Inside the store, Mrs. Jelinsky is complaining that the microwave is broken, and that she can't heat up her burrito. Clyde attempts to heat the burrito up by putting it under the automatic hand dryer in the bathroom. Mrs. Jelinsky gets impatient, and Lincoln helps by putting the burrito in front of her car's exhaust pipe, heating it up, and satisfying her. At this point, the two begin to compete. Lincoln offers to help another customer, which is Darin McGowan, and tells Clyde that he can help with the next one. A bus containing Lynn's sport team approaches the gas station, and Lynn gives Clyde a list of all the requests the team wants. Lincoln wants to help, but Clyde says he's got this and he succeeds in giving each athlete their desires.
Flip then orders the boys to come into the store, saying that he has made his mind on who to promote. He chooses Clyde, much to Lincoln's dissatisfaction. Lincoln then approaches Flip, saying that it's unfair that he gave the promotion to Clyde and not him. Flip says that he has an opening for supervising manager, and Lincoln says he'll do anything for the opening. Lincoln can be seen digging his hand through the nacho cheese dispenser to find the source of a clog, and finds it: one of Flip's missing socks. Because Lincoln succeeded in completing the task, Flip confiscates the unlimited Flippee from Clyde and gives it to Lincoln. Soon afterwards, the two boys begin to do tasks so they can win the unlimited Flippee cup, as well as increasing the promotion, such as:
After having one too many Flippees, Lincoln and Clyde have to use the restroom. However, the two begin to fight when they can't decide who should go first. As the two fight, they hear Flip talking to someone on his phone saying how a couple boys will do anything for Flippees. Realizing they have been used for his own personal benefit, the two reconcile and Lincoln has a plan to get back at Flip.
When Flip tells the boys to help him stuff a fish via taxidermy, the two tell Flip that because of their senior positions, they were granted access to the store's security footage, which contains footage of Flip doing unsatisfactory and potentially hazardous stuff around the store, such as:
The two intend to post this footage on the internet, and Flip, not wanting his store to lose its reputation, says he'll do anything to prevent the footage from going viral. Lincoln and Clyde then instruct Flip to do the same tasks that he made them do earlier.
As Lincoln and Clyde relax, Lynn's sports team comes back, and one of Lynn's teammates uses the bathroom in a panic. The two then instruct Flip to clean the mess in the bathroom, and as Flip enters the bathroom, he is horrified to see the mess, and yells out "Holy nachos!"
