2 + 2 = Physics Mixer?

The Physics Mixer had the best drinks by far. Something Purple that they named Verbatim (sp?). Not sure what it was but it contained Sour Puss and Blue Curacao.... Yum Yum. By this time I'm feeling a little tipsy. Too many drinks consumed in a very short period of time. Had our drinks and left... the Physics majors were trying to do Math calculations on the board... life of the party and all that :D
