S1·E6 Road to Wasabi

Rudy throws himself a birthday party, and an unprepared Jack scrambles for a gift. When Kim reveals her gift to Rudy, an autographed picture of Bobby Wasabi, Jack one-ups her and recruits the former international movie star Bobby Wasabi to make a surprise visit. Unfortunately, Rudy doesn't recognize his hero and is fired from his job after he accidentally flips Bobby. So Jack and the gang visit Bobby's mansion to convince him to rehire their sensei. Jack and Kim are with each other most of the episode, including them fighting ninjas with each other. Rudy takes a job at Reptile World to make ends meet.
