We do a Teeter totter-athon with the Pikes, and we teeter totter non-stop for 3 days....not much fun in the rain!
Also, during King of the Jungle week, a really good event that we did this year was a nintendo tournament between the fraternities....(boys and their nintendo games!

)
Other philanthropy events that others have done are paintball tournaments, "brownies and backrubs", pike fight nite...sorority vs. sorority...frat vs. frat (my favorite), date auctioning, and others.
