"Dancing With the Stars" competitor Kirstie Alley experienced a slight fall from grace on Monday night's episode after her pro partner Maksim Chmerkovskiy's thigh gave out during their rumba routine. Which just goes to prove -- no matter how much you practice your dance moves, sometimes gravity is the ultimate victor.
Perhaps the pair should have chosen Culture Club's "I'll Tumble 4 Ya" as their tune instead of "Somewhere Over the Rainbow"?
Watch Kirstie and Maksim hit the dance floor in more ways than one in the video above.
