South ParkYes, people found a way to even spoof South Park.
Pure stupidity and boredom.
It might become part of a big South Park video project that I'm doing...I dunno
Note: I do not actually think that Cartman is gay! This is just dumb tomfoolery on my part.
Also, they have ears because that is one of those things in the show that shows that the characters are older than children (basically, in this flash, Butters and Cartman are over 9 years old)
