The worst ever "mandatory fun" activity was Win Jeff Park's Candy during 1999 at Lancaster. It was a horrible take-off of Win Ben Stein's Money only based around the (awful) site director. No one could figure out the rules, most of the kids involved didn't know the trivia, and there was nothing interesting to do, so it degenerated into a grass orgy and lots of yelling and screaming out the wrong answers. To placate us, the counselors turned to throwing handfuls of candy at the audience at random intervals. (It really hurt.)

Luckily for all of us, there was a new site director the next year and with it, more interesting mandatory fun activities such a karaoke (not great, but easier to sit through when you're laughing your ass off at your friends)
