You guys talking about GF Stars reminds me of when I was at work the other night and I was asking the one customer if he'd believe me if I told him that my mother had affair with Robert De Niro 9 months before I was born. They got a kick out of it. I wish it was true, though.
Here's an old page with Prank Calls. You have to listen to DeNiro, Pacino, and Pesci. They make me laugh everytime I listen to them.LOL.
