"Ben Stiller and Vince Vaughn were pitching a fourth Lord of the Rings movie to PJ, saying that the feel there is more milk in the LotR "teet" to suckle. PJ insisted that the trilogy was over, and the Ring was destroyed. They gave thier various ideas for a 4th movie. PJ's reactions were just dead pan. I suppose if you get a kick out of Stiller and Vaughn, it's funny. I do. I think it's hilarious when Vaughn winks at people."
