Monday was the last night of musician/god Prince's run of concerts at Madison Square Garden, and because he is Prince, and does what he wants, he invited large-busted socialite Kim Kardashian to dance with him onstage (around 1:00 in the video). But she didn't dance! Instead, she stood there and pulled that awkward-pretend-laugh-oh-God-I'm-so-uncomfortable move that is a favorite of people who can't dance, or don't want to embarrass themselves trying.
But you don't do that to Prince in front of a sold-out crowd at Madison Square Garden, no matter how many sex tapes you have. So he kicked her off stage unceremoniously, and the moment was recorded for posterity in this delightful video.
