If Facebook is the amusement park of the internet, its groups are the rides. I mean, can you imagine 6,000,000 people on a Ferris wheel? I am right now and it's causing my heart to palpitate! Which is why, I suppose, I'm a fan of the groups that only have a handful of members like, "I Wish Phil Hartman Was My Cool Uncle." Just kidding, that group doesn't exist (but it should). For some actually crazy groups, check out this slide show and be sure to vote for your favorites.
