Sean Penn guest starred on Friends last night and now according to E Online, Brad Pitt has agreed to do the same. The husband of Friends' star Jennifer Anniston will play a high school friend of Monica (Courtney Cox) was used to be fatter than she was. For the flashback scenes, Pitt will wear a "fat suit" which appears to be the funniest "not funny" thing on any screen these days (Shallow Hal, Klumps). Pitt's character will obviously not like Anniston which will create fun around the old water cooler the following day. "The funny this is is that he hates her on the show but loves her in real life." There is no word of future appearances by David Arquette on the NBC sitcom. One of the writers was quoted as saying, "we want people to watch the show, not vomit and turn the show off forever."
