Can't believe we're on page 24 and no one mentioned this, but be sure on Thursdays to get really drunk and walk around Helser late at night talking to people while only wearing underwear. If I remember right, 7th floor has more girls on it.
Don't worry if you swing in to say hi and they walk over and suht the door. It's the ones who can carry on a conversation with a stright face at that point who you should go back and meet sober.
Also, beware that doing this might lead to one of your neighbors getting waaay to excited about it. Mine was the guy across the hall, and his hug on move out day lasted just a little too long. Price you pay for having fun.
