He has Tourettes Syndrome. He is friends with Eric & Harold. He likes Frosted Flakes. He insults nearly everyone. AGK got insulted for no reason. Bob Saget is a swear word of his. He screamed it when the TV wouldn't turn on. Tourettes never really excuses his actions though. He made Red think he was a doctor, then put Hal in the oven. He harassed Nicolas over toothpaste he didn't like. He wanted a refund.
