You're a Phi Mu and you don't know what Dance Marathon is?
Although I suppose that makes sense, if you don't have one at your school.
Correct me if y'all are talking about some OTHER Dance Marathon, but the Dance Marathon we have here (and at several other NC schools) is to benefit Children's Miracle Network. Basically it's a 24 hour dance-party-athon type thing. You get pledges, like any other -thon fundraiser, and then you stand for the entire 24 hours. In our chapter, we say, "Remember, you're standing because there are kids who can't." Anyway, it's a BIG deal. Obviously, Phi Mus are very involved with Dance Marathon, but most clubs/organizations on our campus participate. Ours is in April and we've already started planning!
