Injured Dancing

So a friend of ours has the unique talent, despite being a BIG guy, of being able to do the splits.  Last weekend he and his wife won a "People's Choice" award at "Dancing in the Clover" (a "Dancing with the Stars" type event benefiting the Union County 4H).  During the final dance, he did the splits-not once, but twice!

Injury free.

I'd STILL be in the hospital.

Which leads to this...have you ever injured yourself dancing?
