Behind the Scenes of "Scott Tenorman Must Die"
They all wear clothing of varying appearance, however their basic outfit is the same: pants, a shirt or coat, and an undershirt, however, two members of the band do not wear a shirt or coat.
They seem to be caring, leaving their work just to visit Scott Tenorman, due to a letter Cartman sent that claimed he had "ass cancer". However, this is later revoked when they see Scott crying. This lead to them insulting him and leaving.
