Kirstie Alley broke her partner on Dancing with the Stars

Maksim Chmerkovskiy had to know he was playing with dynamite when he took Kirstie Alley as a partner on Dancing With The Stars, and last night his hubris finally cost him (clip above, full video here).

Us magazine says...

No pain, no gain for Maksim Chmerkovskiy.
The Dancing with the Stars pro suffered a mysterious injury on Monday's performance show -- and nearly dropped parter Kirstie Alley when his thigh gave out.

Mysterious? He's from earth and he tried to support 600 pounds of sloshing gummi bears on his thigh. I have a theory as to what caused his injury! You wanna hear it? I'm gettin all House and really thinkin outside the box on this one!

Although Chmerkovskiy, 31, was all smiles on camera, the dancer appeared to be in considerable pain during commercial breaks -- grimacing and apologizing profusely to Alley, 60.

"Sorry for not being Wolverine with rods of unbreakable metal for bones."

"No big deal," Chmerkovskiy said in a chat after the show. "I'll be fine... It'll take a stretcher to get me out of here!"

I think that was his polite way of asking for a stretcher and ambulance before chips of his pulverized bone get lodged in his heart.
