As a response to new safety regulations for his son's football team, Stan Marsh suggests that everyone play a safer, friendlier sport called sarcastaball instead, which becomes an inadvertent national success, sarcastically.
Randy: Yeah, the players should all wear bras! And instead of helmets, they should wear little tin-foil hats, because you know, it's the future, and we shouldn't be so barbaric! Principal Victoria: How will the bras and tin-foil hats make it safer? Randy: Oh, you're all not getting it, see, while we're at it, we'll have a balloon instead of a ball, and whoever catches the ballon will tries to run while all the other players hug!
