Speed drinking is never a good idea, and will never have a good ending.  The weird thing about this video though, is that the drinker isn't the only one who gets the backlash from his speed drinking challenge.

This is the only guy I've seen take a speed drinking challenge and not have anything bad happen to him.  I think he might have had something wrong with him going into the challenge though, so I don't think he even counts.
