Vince Vaughn Works Out With 95-Year-Old Jack LaLanne (VIDEO)

Jay Leno put Vince Vaughn to work earning his plug for his new movie, 'Couples Retreat.' Vaughn was forced to work out at the hands of 95-year-old fitness icon Jack LaLanne.

"Now Jack, I want you to whip this candy ass into shape!" Leno said.

LaLanne coached Vaughn through a series of dips on a metal chair, which he executed gamely then kissed the old man on the cheek.

'Couples Retreat,' in which Vaughn plays a happily married man on vacation with friends who are trying to save their marriages, opens October 9.
