I get obsessed with a few things every now n again... At the moment, it's with collecting.
Stickers, postcards, and branded beer glasses are the current fetish. I love them. The laptop I'm posting this on is covered with the contents of Sticker Bomb!
A while back, it was measuring every rectangle in sight; to see how many were governed by the Golden Ratio, or Phi.
Anyway. There's one t.v show I have a slight obsession with, and that's Mythbusters. I love it. The two presenters (Adam Savage and Jamie Hyneman) have both led awesomely interesting lives. Read a bit here. Here is Adam talking about his obsessions. Winner.
