Jeremy Piven is best known for his scene-stealing performances as Ari Gold during his eight season run on the hit HBO series Entourage.
But lately, the New York City native has focused largely on his stand-up comedy career, with the Emmy winner hitting the stage at Comedy Stars Under The Stars For Prostate Cancer in Santa Monica on Thursday night.
