2. Anger Management
Episode: 'TMI' (S15) Cartman is sent to anger management therapy when he measures all the boy's penis sizes and posts the results on the school bulletin board. His scheme to overthrow school hierarchy backfires when it is revealed he has the smallest one. At an anger management session, a therapist tries to provoke Cartman into anger by calling him nicknames, like fatty and little fat s**t. Cartman just takes out his phone and starts texting. A minute later, the therapist gets a phone call. It is his wife, who accuses him of going on a webchat with an underage boy. She then promptly kills herself. This was all Cartman's doing, and this one evil act is underplayed in the episode. This shows how Cartman has escalated throughout the series from a naughty little boy to someone who is actually dangerous.
