21. Matthew McConaughey
We suppose that if we were as chiseled as Matthew, we'd spend our days shirtless — and do a zillion cheesy shirtless movies — too. But it seems he's gotten so used to not getting dressed that when he must put together an outfit of actual clothing, he simply doesn't understand the concept. Which is a shame, because when he sets down his bongos and hires a stylist, he's the coolest stoner on the red carpet.
