The Washington Post has also picked up on the Wolf Shirt phenomenon. It appears College Humor is claiming credit for the uptick in sales. Anyone know the timeline? I'd be curious to know if the "sextuple dog dare" came before the College Humor prank or vice versa. Either way, I'm going to go out on a limb and say that WWDC attendees probably make up a good solid chunk of those Wolf Shirt purchases. It's one thing to ask people to vote in a poll, another to spend $15 to buy something.
Oh, and the shirts have apparently sold out, as well.
