Here's a preview clip of tonight's Real World episode in which two of the girls (the "ethnic" one and one of the boobie blondes) get in a fight over a guy they both kissed. It starts off with the one girl puking in the confessional, and then almost immediately pulling herself together to throw down with her roommate/nemesis. We must admit we're somewhat impressed with her boot and rally capabilities.
I don't trust there was actual puking. The MTV/VH-1 folks are truly masters of editing. I'm guessing fake puke sound added after the fact (I think they did that with Lacey too... we never saw puke).
