Thad Jarvis is an expert Guitar Hero player. In the episode "Guitar Queer-O", he is selected by a talent agency to score one million points in the Guitar Hero game with Stan Marsh. However, he quits when Stan gets addicted to Heroin Hero and becomes a crabby jerk. One of his notable feats is playing two songs ("John the Fisherman" and "Jordan") on the controller without the game so well that other people can hear him and compliment him on his skills.
