Tapping a keg takes a pro. Not someone who pretends to be one... but someone who's actually done it before. And they probably shouldn't already be drunk...
This guy had to do some real work to get it tapped... and with the pressure of all his friends watching and anticipating their new beer.... they laugh as a stein is broken, but they don't realize the real tragedy about to happen.
BONUS PRO TIP: Don't do backflips while drunk and in front of a crowd.
