Here's a cute little video that is very Jackass in nature and I'm posting it here purely for it's entertainment value. Yes, it's definitely fake for those of you who don't notice the wake that the shark fin is gliding through (suggesting to me that whatever that is, it's being towed by a boat). I doubt nearby surfers would be as calm as hindu cows with a shark that big hanging around either. Fake as it is, it's still funny. I reckon if Stevo (from Jackass) saw this, he'd probably go forth and do it for real.
