The homeless guy has appeared in several episodes. First on the episode Spirit Journey Formation Anniversary when Shake needed money to pay off Zakk Wylde for the recording, editing, and playing of the song "Spirit Journey Formation Anniversary". Because of Shake's lack of money he put Meatwads room up for sale (similar to the episode Mayhem of the Mooninites.) The homeless guy shows up and starts babbling incoherently, and when Shake goes to show the homeless guy the room he steals their TV and muffins and runs off.
The second time was in Gee Whiz when he appeared on the billboard with the picture of Gee Whiz (which really was Ted Nugent). Initially he announced that Frylock was Gee Whiz, then decided he must be Gee Whiz. When Master Shake asked him sarcastically if he could fly, he promptly jumped off the billboard screaming and hit the pavement face first, killing himself.
He asks Meatwad to bring him a Daiquiri in jail by smuggling it up his butt in the episode Bart Oates. He was shot and killed by Carl during the episode Robots Everywhere, but returned in "Piranha Germs" since ATHF has no continuity.
