While out with friends in Venice over the weekend, Vince Vaughn was brought up to speed with celebratory hand gestures. The Rudy star felt the need to high five after joke he made, but his friend told Vaughn that all the kids pound it or bump knuckles these days. The friend quickly taught the basic elements of pounding to Vaughn which he enjoyed. Vaughn said, "I can see why everybody likes this. Cuts down on the germs."
