Zeke and Luther are preparing to set a new butt-boarding record. And things seem set until their training gets interrupted by Luther's new-found fascination with cup stacking. Possessing a natural talent for the sport, Luther fakes a stomach ache so he can get out of butt-board training with Zeke and enter a local cup stacking tournament. After learning that Luther has won the cup stacking tournament, Zeke enlists Stinky Cast (from "Luck Be a Rodent Tonight") to be his new butt-boarding partner. In the end, Luther chooses skateboarding and his friendship with Zeke over cup stacking and guacamole-limousine parties.
