Bristol Palin Rips a Man's Shirt Off While Her Mother Claps Meekly

Famous for getting knocked up, then denouncing copulation, Bristol Palin is determined to keep her sex life in the public eye. On Dancing with the Stars last night, she ripped a man's shirt off and humped him in slow motion.

Bristol's rumba begins with her lying supine on the floor. (Literal horizontal mambo?) Dance partner Mark Ballas sweeps her into his arms and they proceed to hump, slowly and rhythmically, as Bristol rips his clothes off and grins.

I think we all got more insight into the conception of Tripp Johnston than we intended last night. That closing image of the Palin clan smiling and clapping afterwards is priceless.
