Conference parties

Well, as a new soapbox blogger, I thought I would start at the epitome of geekiness: the "underground" conference party.  As a recent attendee of such a glorious event, I would just like to say "wow."  Not only have I never seen such ridiculous dancing, I also haven't ever been in a situation to see so many of my colleagues drunk and hitting on girls half their age.  Generally, it was a very fun time, even if you were just watching the old guys strut their stuff, so to speak.  This was my first time at an event like this and it was definitely an eye-opening event.  Are all conferences like this? I would love to know if physicists get down with their students like the astronomers do.  Also, can we have one of these parties in the department?  That would be very interesting...
