During the 1970s, Arnold Schwarzenegger was finding great success in the world of bodybuilding (and enjoying it so much that he compared it to cumming), but mega-stardom in Hollywood had yet to be attained. At this time, Schwarzenegger was still forced to take supporting roles and small bit parts in films and television shows, including a 1979 flick called Scavenger Hunt, a Rat Race/It’s a Mad, Mad, Mad, Mad World-style screwball farce about an ensemble cast entering a scavenger hunt to claim a large inheritance. In this scene, Schwarzenegger plays a gym instructor named Lars, who puts Tony Randall through a strenuous workout and throws a medicine ball at him so hard that he knocks Randall out a second-floor window.
