How about something unique that teams can appreciate? Video games and music are great, along with munchies and the like, but how about something active... like a game of Ultimate Frisbee or Manhunt or Black-Light Volleyball? or how about a huge pit of legos and a contest to see who can make the most creative thing in 50 legos or less? the winner gets a pie to the face! except you dont tell them that until
after they've won.

or maybe find a way to teach us how to do something new and not exactly robotics related? like (please dont shoot me with a poof ball for this suggestion) ballroom dancing?
Think outside of the box.
