It's been a while since I've been to one....8 or 9 years (last bachelor party, I guess). But, I'll NEVER forget the show....it involved a giant champagne glass - filled with water - and a stripper that was an alleged former Olympic gymnast. The audience was literally drenched when the show was over!
Fortunately, I was still getting the first round at the bar while the show was "in progress", so I missed the up-close and personal involvement.
