I've used the toilet paper game, many, MANY times (almost every college organization I've ever been in!). I heard that the M&M game was used by one sorority during last formal rush. It was something like every yellow you had to name a person who influenced you, for every blue a favorite song, etc.. I don't want to sound like a dork, but I love icebreaker games... you get to know so much about other ppl, and get to share things about yourself!
