Other mistake: Everyone in the entire game (including the Koreans) has no armor on except for the boys and their friends from school.
Other mistake: Butters tries to get a "seamen sample", and is on it for two days straight. The mistake: You can see Butters' head in the school classroom, while he's still supposed to be in Cartman's bathroom. (00:15:30)
Other mistake: When the boys cause a mini tremor by blowing up the girls' base, the time at which it occurs is strange because when they do it, both Stan's parents are at home (even though they both have jobs), Ms. Choksondik and Mr. Mackey are at Choksondik's house getting it on (indicating that school is over) and the other teachers are still at the school.
Other mistake: Whenever Chef has his pointer finger up, if you see his hand, he has 5 fingers, but when he opens them all the way, he only has four.

The Tooth Fairy's TATS 2000 - S4-E1

Other mistake: In "Broadway Bro Down," when Shelly and Larry are playing Settlers of Catan, Shelly tells him, "And I got a victory point for the most roads connecting settlements." In the game, there's a two victory point bonus for the longest road, but no points for getting the most roads. (00:14:10)
The Biggest Douche in the Universe - S6-E15
Other mistake: When the trailer for 'Kenny' is being shown, the label on the pot roast has McGilroy written on it, instead of McElroy (which is Chef's actual surname).

The Succubus (a.k.a. Chef's Mama) - S3-E3
Other mistake: Cartman says, "What? What happened you guys? Is Kenny okay?" The bandages only covered his eyes, not his ears, so even if he's blinded by his bandages, he still should have been able to hear Stan shouting, "Oh my God! She killed Kenny!" and Kyle's reply "You bastard!"
Osama Bin Laden Has Farty Pants - S5-E9
Other mistake: When Stan goes to answer the door after telling his mother that the doorbell is ringing, he clips through Sharon's arm. (00:04:31)
Other mistake: At the Children's Therapy Center, a girl says she has a tick that makes her bend her neck and snap her fingers. In this shot, Thomas and the girl sitting next to him are reflected in the mirror behind her, but their reflections are not backwards like they should be. This is shown a few more times in following shots. (00:07:57)
Other mistake: When the camp guards take the internet away, the computer cable being dragged away is not plugged into anything, even though the computer was on. (00:17:15)

Answer: He appears in at least 5 other episodes, but usually just as a background character. He can be seen at Cartman's party in "Immaginationland". He was also one of the kids trying out to replace Butters in the "Professor Chaos" episode.
