Video: Ellen Crashes the US Open. You Gotta Watch. Seriously.

While in New York, Ellen Degeneres visited the US Open and all types of hilarity ensued.  She played tennis with Melanie Oudin, crashed Venus Williams book signing, taught the ball kids, and made drinks for fans while drinking a bit herself.  

My favorite part? When she puts two shots into someone's Honey Deuce, (a fab drink the sell at the Open) instead of one and calls it mixed doubles. Hmmmm......doesn't sound so funny when I type it, but really funny to watch. Promise!
