Insecurity - S16-E10
Continuity mistake: Cartman walks into his house and can't remember the code to turn off the alarm, so he gets a call from the security company. When the man on the phone introduces himself, the clock on the wall to the right of shot reads 2:02, then the time changes to 12:37, then back to 2:02 again.
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.
