'Entourage' smackdown

Same: Celebrity feuds

Vince isn't as easily riled as Mark, but the two do share a history of celebrity feuds. Seth Green plays himself and a recurring foil on "Entourage" to mess with Vince and E, one time causing a brawl at a Vegas nightclub. As for Mark, Andy Samberg's recent spoof of him on "SNL" ("Say hi to your mother for me!") inspired Wahlberg to tell Jimmy Kimmel he'd "crack [Andy's] big f***ing nose." No worries, though. The two made up when Mark appeared as himself in a second skit.
