A group of teenagers (all of whom easily look to be in their 20s) decide to attend a sideshow carnival. You have your typical characters: Horny Guy, Ice Princess, Handicapped Brother, and their mom - I mean Ice Princess's Best Friend. They wander aimlessly eating plain hot dogs until they decide to go to the titular Sideshow, easily the most interesting thing in the movie. Then, somehow, they decide it'd be a great idea to go into the sideshow after it closes. Maybe to eat more bland hot dogs? Or maybe it's because that gives the audience the chance to see the glorious Phil Fondacarlo chew up more scenery.

To be honest, this is actually a pretty fun film to watch on its own, but would still make for a great riff.
