Cartman begins to wonder why all the kids at school except for him have fathers. When confronted by her son about the father, Mrs. Cartman recalls the night when he was conceived at the Drunken Barn Dance where she had sex with just about every man in town. Dr. Mephisto reveals that he can perform a DNA test to determine who the father really is for $3,000. Eric tries to raise the money with the help of Stan and Kyle by sending a video to America's Stupidest Home Videos. He becomes annoyed when he realizes that the video is deriding him, though the video wins second place and a $3,000 prize.
