It's official: Kmart's new "Ship My Pants" TV commercial is a viral video hit. There's even a #ShipMyPants hashtag on Twitter. The premise of the funny ad is simple: the word 'ship' sounds an awful lot like...well, you know.

Throw in a kid who gleefully informs his father that he can't wait to ship his pants and an elderly woman who explains how shipping her pants is "very convenient" and you have a recipe for a good time.

Oh right, there's also some sort of marketing message about having the stuff you can't find in Kmart stores shipped to you for free. But who cares about that?
