Constantly bragging about the beast lurking in your pants? Here's your chance to unleash it on the world.

Levi's has the newest entry into the viral marketing arena with their Unbutton Your Beast website, where you can choose a trouser creature, select a pre-made message or instantly record one of your own over the phone, then unleash your beast on anyone you like.

Recipients get a link to your custom-created video, where they'll be greeted by a bodyless pair of 501s that unbuttons to release Trout Troutman, Sock Nasty (pictured), Cookie the Cougar, or whichever of the nine or so pant-dwelling beasts you chose. (What, no snake-based beast?)

To send one to whoever was curious about what you're hiding down there, head over to www.unbuttonyourbeast.com.
