Madonna had an onstage mishap at her Dallas show on Sunday, Oct. 21. Madge was interacting with the adoring crowd during the smash hit 'Like a Prayer,' kneeling before them while the fans sang louder than she did. When she crouched down to engage the crowd a second time, she lost her footing and fell over. Splat! She gives new meaning to the idea of stop, drop and roll in this giggle-inducing clip.
