Cartoon people is funny. Sometimes we get all giddy/bored/drunk and draw our co-workers into the shows. All of our shows for Cartoon Network are chock full of cartoon cameos by their crew members. Witness:
I did some of the storyboards for "Dexter Detention" and as a goof, added a bunch of crew members to this list. The model designer did me one better and stuck me in with the other delinquents.
When an episode of PPG called for a guy who steals some Powerpuff dolls, Stef Choi decided I looked like a criminal & thus my life of cartoon petty thievery began.
