It may be hard for Jon Stewart fans to imagine, but the beloved Daily Show host is "anything but warm and fuzzy," according to staffers quoted in Lisa Rogak’s new biography of the comedian, Angry Optimist: The Life and Times of Jon Stewart. One tells the story of a time Stewart screamed in a producer's face and threw a newspaper at her, only to later apologize and explain, "Sorry, that's bad Jon. ... I try not to let him out." There are more such tales of Stewart's angry side in the book, Forbes reports, and Rogak notes, "I'm surprised that people are surprised by [the angry side]. You look at his delivery on the show, and I can see the seething anger in Stewart."
Stewart also once screamed at Seth MacFarlane, the New York Daily News reports. The book recounts how Stewart called the Family Guy creator after MacFarlane joked about Stewart returning to his show during the Hollywood writers' strike. "Who the hell made you the moral arbiter of Hollywood?" Stewart reportedly yelled. MacFarlane once talked about the experience with Piers Morgan, calling it "an odd Hollywood moment." But, hey, the book also reveals that Stewart lets staffers bring their dogs to work, the Washington Post reports.
