Breaking: Spencer Pratt is an asshole. The resident villain and couch-sitter on The Hills was on David Letterman's little show on Friday night, talking about his high-rollin', baller lifestyle. He said that he demands $100,000 for a one-night appearance at a nightclub. The audience laughed, Dave laughed. It was a funny joke. Except then Spencer was all "naw, dude, I'm serious." And Letterman's expression changed sadly and Spence looked even more like a bratty little kid, slouched in his chair, not getting the extremely loud and glaring joke of himself. Then Paul Shaffer made a funny! Clip is above. [From Jossip]
