I watched that episode. I thought the game was a bit childish but I couldn't help but laugh especially when Julia hit Jimmy so hard in the face with the ball! I don't know what she did but Julia looked very very good.
She looked really good at the Tonight Show. Amazing legs!
And I agree, I don't like Jimmy Fallon either. Some of the games are funny (not the one with Robin Wright, why was that funny?!), and he has nice (famous) guests, but otherwise I wouldn't watch it.
