I'll admit, even as a guy, I'm occasionally curious to know how my butt looks when I'm trying on a new pair of pants. It's partially 'cause I want to make sure they fit right, but let's be honest: it's mostly 'cause I'm vain.

But it's such a hassle to try and get a decent view in those tiny little dressing rooms -- craning your neck around to look in the mirror while you're facing the opposite direction. I swear I pull a muscle every time I try it. And, even though girlfriends, best friends, and other random shoppers could help out by offering their opinion, I'm never convinced until I can see something for myself.

Fortunately, the Hub clothing boutique in Arizona has installed the "butt-cam," that allows customers to make sure their backside looks good before buying a new pair of pants. Genius!
