If you're young enough to have seen Wet Hot American Summer but didn't realize it was a parody, then go to the Little to see Meatballs (Ivan Reitman, Canada 1979, 94 min.)

Mr. Depressingly Unpopular Rudy goes to summer camp full of rowdy teenagers. The head counselor is Tripper Harrison, the prank pulling, girl seducing, fun lover, teasing both his boss and the counselors at the nearby rich kids camp. He and everyone else are sick and tired of always losing the Camp Olympics every year, Tripper must encourage all campers to try their hardest, and even convince young Rudy that this may be his chance to feel better about himself.
