The Rock was on the Jumbotron last night when WWE's Monday Night Raw returned to Buffalo. The Rock was laying the smackdown on John Cena and talking about being the host of Wrestlemania. Which got us thinking why haven't we've seen actor Vin Diesel and The Rock in the same room?Besides different shades of tan, little differentiates the bald, beefy stars from one another, including their movie careers.
