Kirstie Alley falls on Dancing with the Stars

Post-traumatic stress disorder (PTSD) is normally associated with people who've fought in horrific wars or survived unspeakable tragedy, not contestants on reality shows. That all changed last night in Los Angeles. From Us:

[Maksim Chmerkovskiy] pro suffered a mysterious injury on Monday's performance show -- and nearly dropped parter Kirstie Alley when his thigh gave out. 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.

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

After seeing last night's show, organizers of the annual "World's Strongest Man" competition have added the "Two Minute Rumba with Kirstie Alley" to the event this year. In response, 2010 champion Žydrūnas Savickas of Lithuania announced that he will not be returning to defend his crown. "Even I'm not zat fucking stupid!"
