The Attention Deficit Disciple is found in conjunction with the Stop Having Fun Guy, usually as a sidekick or junior partner and generally as the stupider of the two. Whenever the bulk of the cast are engaged in Wacky Fratboy Hijinks, a musical number or some other rollicking bit of fun, the Stop Having Fun Guy will refuse to join in. However, a zoom-out or change of view will reveal that his companion is cheerfully joining in.

- Zatch Bell!: Folgore's first appearance. Kiyomaro is still analyzing him while he dances, and Gash couldn't help but join the dance.
- Occurs in The Rocky Horror Picture Show when Rocky, as well as all the nameless Transylvanians and Columbia, start dancing along to Eddie singing Hot Patootie much to Frank's dismay/jealousy. Instead of stopping in embarrassment, Rocky gets thrown into the elevator by Frank and watches in horror as he kills Eddie with a pick axe.
- The finale of the movie remake of Hairspray does this with Velma and Amber.
- In Enchanted, Robert catches himself bobbing along with Giselle's Crowd Song before realizing what he's doing.

- Iago in Aladdin during "Prince Ali."

- Despite the fact Captain Smollett (Kermit) is actually Mr Arrow (Sam the Eagle)'s superior in Muppet Treasure Island, the bit where Smollett joins in with "Sailing to Adventure" and then immediately stops when Arrow glares at him definitely feels like this trope. (It's previously been established that Arrow wants Smollet to be a stern and ruthless captain, and hates any evidence that he isn't.)
- TV's Frank does this numerous times on Mystery Science Theater 3000.
- The Spongebob Squarepants Movie involves this and a mosh pit.
- In The Simpsons episode "Lisa the Vegetarian", Homer responds to Lisa's new vegetarianism with "You don't win friends with salad!", which Bart turns into a conga line. They leave the frame and when they return, Marge has joined in; Lisa admonishes her, and Marge responds "Sorry, it was catchy".
- Something similar happens in "Two Dozen and One Greyhounds". Mr. Burns sings a song (to the tune of "Be My Guest") where he details how he plans on skinning the greyhounds he adopted from the Simpsons to make a tuxedo. Lisa is horrified, but Bart is humming along, and again, when Lisa calls him on it, he says "You've gotta admit, it was catchy."
- Inverted somewhat in Kiss Kiss Bang Bangalore. When the Indian employees and some other characters break out into a Bollywood song and dance, Smithers looks on eagerly until Burns allows him to join in.
- Max in Cats Don't Dance.
- Occurs in The Great Mouse Detective during the mouse burlesque show, with Basil looking over to see Dawson (who's acting loopy after drinking a drugged beer) dancing with the showgirls.
