Back to Vince. In the second biggest WTF moment of the season (the first goes to Turtle for selling his stock of Avion tequila before Mark Cuban could take it public), Vince recruits Billy Walsh to hook him up with a fake penis loaded with clean pee. Vince confesses the plan to BFF E, and as usual, Eric tells him how stupid he's being. In a turn that only the Mayans could have seen coming, Vince gets the call later that night that his sample, along with his reputation, came back clean. "Airwalker" is still on, the boys can hug and laugh about the close call and "Entourage" ends like it usually does -- free of weight, concern and burden.
