David Blaine

Get out. David Blaine spent a week submerged under water. Then, as if he needed to provide further evidence that he is an all-out nut bag, he made an attempt at breaking the world record for holding your breath while submerged--9 minutes. And for his efforts, tell him what he's won! Yes! David Blaine suffers breakdown of skin tissue, liver failure in addition to a host of other physical ailments! But that's not all! No, you get to spend the next week at the Yale Medical Center so they can study the effects of being submerged long-term on the human body. Outstanding! You have won the exclusive vacation trip for the unabashedly and astoundingly stupid! Seriously, what did this guy suppose was going to happen? On the other hand, you have to admire his willingness to make a spectacle of himself for our amusement.

Nah, he didn't break the record. 7 minutes and 9 seconds. Of course, this all assumes that it was even real. Debatable.
