Lincoln begins to hog the spotlight when he becomes Luan's clown assistant.
The story begins with Lincoln ready to read a comic book under a tree, when Luan appears. She's about to fall from her unicycle, so she cries for help. Lincoln rushes to catch her, but she falls down. Lincoln helps her by collecting her party toys and props from ground. She offers to make him her clown assistant, because the othersistersshecontracted ruined each of the birthday parties she performed for. Lincoln declines at first, but when Luan tells him that the clown and her assistant receive free pieces of birthday cake, he eagerly accepts the job.
At the next birthday party, where he assists, Lincoln accidentally slips on a whipped cream can, and falls on the presents, which the kids see as hilarious. Flattered with the laughs and applause, Lincoln begins to hoard the show by making pratfalls to make the children laugh while overshadowing Luan, who becomes extremely jealous of him.
One day, Funny Business Inc. receives a call from a mother of the neighborhood to contract Luan as a clown in her daughter's birthday party, but Lincoln takes her place believing it's gonna be easy, as with the previous parties, and ignoring Luan's advice that being a clown is about more than just "falling on his butt". When he arrives at the party, he's very surprised to see that all the kids are emo tweens, and the birthday girl, Maggie, is not 4 or 5, but 13 years old. He then begins to do his act, but the emo kids boo him, and don't find him funny at all. Humiliated, Lincoln calls Luan for help, but she refuses at first, due to his selfish attitude towards her. He apologizes and recognizes that she's the expert and he isn't, and also tells her that if she doesn't come, her clown business will have a bad reputation, and she finally agrees to help him.
Luan finally comes to assist Lincoln, and after looking at the audience, she gets an idea. She and Lincoln perform a mime play, which all the emo kids enjoy and clap to. On their way home, Lincoln thanks Luan for her aid, and apologizes to her for his misbehaving. She forgives him, remembers when she got her first laugh, apologizes as well for being too harsh on him, and asks him if he will continue being her assistant, which he agrees to. In the end, they both enjoy a moment of laughing together after they do a couple of pratfalls on some whoopie cushions.
The title of this episode means unpleasant, or dishonest actions, which seems to describe both Lincoln and Luan's actions throughout the episode, and the fact that the episode's central theme is clowns.
On the title card, Lincoln's chipped tooth is noticeably dislocated.
Luan's assistants prior to Lincoln and the reason they were fired:
Lucy - Scared Luan and the other kids, causing her to pop the balloon animal she was making.
Lynn - Threw a watermelon at Luan too hard during her juggling act.
Leni - Stopped assisting to watch the show.
Leni is the only former assistant to be older than Luan.
Lisa - Thought the whoopie cushions were a case of gastroenteritis.
Ctrl+Alt+Del - Inside of Luna and Luan's room, a blue poster resembling the infamous "Loss" comic with stick figures can be seen.
This is the second time since "Cover Girls" that the Marx Brothers' "mirror routine" has been referenced.
Phone Hanging - When on the phone with Lincoln, Luan makes phone static noises with her mouth, and tells Lincoln that the connection is bad, so she can hang up. This has been in many other movies. Some examples include The Parent Trap, Pee-wee's Big Adventure, and Star Trek VI.
LOL - One of the mothers use the well known term when referring to one of Lincoln and Luan' acts, which actually means "Lots of Laughs" and/or "Laughing Out Loud".
Loss - In Luna and Luan's room, there is a poster of a 2008 notable webcomic titled "Loss".
Lynn's business ID card shows that she has two freckles on her left cheek instead of three.
When Lynn and Lana are laughing at one of Lincoln's pratfalls, the FiOs captions said LENI and Lana were laughing, instead of LYNN and Lana.
While at the fifth birthday party with Lincoln, Luan gets angry, and when she shows her teeth, her braces are missing.
Not only that, but that party had a medieval theme, but when it shows Lincoln being admired by his fans afterward, it changes to a pirate theme.
When Luan arrives at Maggie's party, her eyelashes are missing.
In the flashback to the first birthday party, Lucy stays in her regular attire instead of an "assistant" black outfit like Luan's other assistants.
In the panoramic shot of Maggie's birthday party and its following shots, there are several continuity errors:
The piñata and the disco ball suddenly appears in the following scenes after the panoramic shot.
The arrangement of kids texting with their smartphones in one scene was different in the panoramic shot.
The piñata and the disco ball are not hanging from anything, making them look like they're floating on mid-air.
Two kids are shown being standing up in front of the stage, but then they are showing in the piñata scene. Additionally, the blonde hair girl with a wool cap is shown in three different consecutive scenes of the party.
In the panoramic shot, there are two cakes over the table next to the stage. However, when Lincoln falls on the cake table, there is one cake and a tray with muffins instead.
