Cooper prepares for his big Bar Mitzvah while Alex switches places with a skate-boarder named Mitchie Brusco who looks like him (because they both have a mole on their upper lip). While Alex gets to meet Tony Hawk, Mitchie must go to Cooper's Bar Mitzvah. At the Bar Mitzvah, a tape is shown where Nat, who is on too much laughing gas, reveals Cooper's secrets. This sends the party into a disaster, so Nat decides to have the band perform but discovers that Alex is really Mitchie. Meanwhile, Alex gets into trouble when he challenges Tony Hawk to a skate off. Alex and Mitchie both decide to fake injuries and they switch back.
