Halfy

 Halfy (pronounced Half-ee) is an amputee (he has no legs, hence his nickname), who first appeared in the episode "Cartman's Mom is a Dirty Slut". In his early appearances, he would claim that he would have sex with various things/people, only to be told, "You don't count Halfie; you don't have any legs", to which he would reply, "Oh. Yeah." When he is happy, he jumps into the air and does somersaults.

Halfie can be spotted at the starting line of the South Park "Running of the Cows" in the episode "Cow Days". He is also mentioned by Big Gay Al during his big musical number in South Park: Bigger, Longer & Uncut. He appears in the episode "I'm a Little Bit Country", singing, "I'm a little bit country, I'm a little bit rock and roll".

In "Conjoined Fetus Lady", Sheila Broflovski read the boys a book about freaks. On the cover page, a man who looks exactly like Halfy, only with grey hair, can be seen.

Judging by his looks, he may or may not be a reference to Lt. Dan Taylor in the movie Forrest Gump from 1994.
