That crazy girl Miley Cyrus (she's crazy!) revealed on Instagram yesterday that she has a new business venture: Billy-Bob dentures. You know, those gross-looking fake teeth that people wear for laughs and fun. Miley modeled the line in the nude with illustrated chicken wings affixed to her breasts.

Why? Why not? Honestly, who knows. The world is a cold, confusing place and Miley Cyrus is just barreling through, drooling into her bumpkin snaggleteeth.

Unfortunately for you, the Miley-Bob teeth ($12 a pop) sold out within hours yesterday. Miley wrote on Instagram in celebration: "Fuckkkkk yasssss #mileybob teef alweadyyyy sold out."

What will that crazy girl do next?
