Stan and Kyle build a clubhouse so they can play Truth or Dare with the girls Wendy and Bebe. Cartman and Kenny get together to compete with the two and set about building their own. Randy and Sharon temporarily separate.
At Stan's house Stan is stopped from watching Terrance and Phillip on television in favor of the, unbeknownst to Sharon, equally vulgar Fat Abbot Show. Meanwhile in the kitchen, Sharon's dropped her wedding ring down the sink and demands that Randy gets it out. After a small argument Randy accidentally calls her a cunt, and Sharon goes mad.
At school Bebe hints her like for Kyle by passing notes. Stan is caught with it by Mr. Garrison and is forced to read it out loud to the class. Not realizing the note was from Bebe, the class is shocked to hear Stan's "attraction" to Kyle. Stan is then sent to Mr. Mackey who calls in his parents. This causes Randy and Sharon to inadvertently argue with each other and they finally end up separating.
At Stan's, Sharon introduces Stan to her new partner Roy, Stan is shocked at the unusual pace of events but goes back to building the clubhouse. Unfortunately Stan is delayed by having to spend quality time with Randy and having to get firewood for Roy.
Meanwhile, Cartman and Kenny's clubhouse is complete, and Kenny gets two teenage girls to stay there. The girls then invite all their friends over and the party goes out of hand with Cartman unable to play Truth or Dare. Cartman becomes extremely agitated by his unwelcome guests and watches in horror as Kenny is trampled to death in a mosh pit.
After Roy being an extreme nuisance, Stan watches a Fat Abbott cartoon and discovers that to get back at nuisance step-fathers you should leave a note to meet them somewhere and lay down a bear trap.
Roy reads the note and goes to the clubhouse to meet Stan but is caught in the trap. Sharon and Randy also read the note but go to the clubhouse. It reminds them of when they were kids playing Truth or Dare. Sharon dares Randy to have sex with her and they make up.
The next day at school, Bebe tells Kyle that she wants to break up to be with Clyde. Later Wendy, Bebe, Clyde and Stan are in the clubhouse playing Truth or Dare. Stan chooses dare and instead of getting to kiss Wendy, he has to shove a twig up his "pee hole". Roy is left hanging as this all goes on.
