During the scene when Van and his friends are riding in Van's golf cart, just after Van has sex with the secretary, the guy in the back is seen being licked on the face by the bulldog. When the camera cuts to Van he's not being licked. When the camera cuts to Van's assistant he's being licked again. This happens over and over.
It's said that Van has been in college for 7 years. This is a nod to a line from John Belushi in "Animal House," when he says, "Seven years of my life for nothing."
