Jeremy Piven has reportedly been banned from all restaurants owned by Asian chef extraordinaire Nobu Matsuhisa after behaving like not just a jackass, but a tightwad, self-promotional jackass, at the Aspen Matsuhisa during the U.S. Comedy Arts Festival:

[Piven] came in with a large group of 12 or more without reservations and asked for a table. It was a very busy night, but a table, although cramped, was provided. On his way out, he made a nasty comment to the manager: ‘Thanks for nothing.’

Piven was at the HBO-sponsored festival to appear on a panel with fellow “Entourage” stars. Allegedly his tip also left something to be desired.

“He left a DVD of the first year of ‘Entourage’ to one of the waiters. [An employee] ran up the stairs and hurled it at him as he was leaving.”

Ahhh, Piven. If only that box set had connected with that big head of yours. If it didn’t succeed in knocking some sense into your melon, it might at least have provided some comic relief by sending your dead rodent toupee skittering to the floor.
