The Tourette's Tolerance and Understanding Foundation is a support group for people with Tourette's Syndrome, which was seen in the Season Eleven episode "Le Petit Tourette".


The South Park branch of the organization is run by a man called Mr. Donaldson. He took Kyle Broflovski to the organization to meet and talk to people with Tourette's after Kyle protested that Cartman was faking having the condition. There, Kyle met several other afflicted children, as well as Thomas, who later helped him expose Cartman's charade.

Thomas has a light yellow shirt with green stripes and dark green trousers. He has dark blonde hair and faint bags under his eyes. Thomas suffers from regular outbursts of swear words, primarily "cock" and "shit," wherever he may be, which is not helped by his mother who tries to integrate him into society when he has a series of outbursts in a toy shop.

Main article: Mr. Donaldson

Mr. Donaldson has short, brown hair. He wears a white shirt under a brown suit, a green tie, and dark gray pants. As a sufferer of Tourette's himself, he has his own verbal tic - randomly saying the words "piss" and "ass" (particularly spouting things about things going in or out of his ass). He also seems very devoted to teaching others about Tourette's syndrome, even to the point of ignoring any evidence that someone would be faking it, as well as claiming that anyone who thinks otherwise is a "bully".
