Jon Stewart isn't just America's most trusted newscaster, he's also a husband and father of two children.

Jon says fatherhood presents special challenges for a comedian. "It is an amazing opportunity to be able to ruin someone from scratch. They will believe anything you say," he jokes. "How do you not prank such innocence? 'Daddy, are there monsters?' 'Oh, there they are!'"

Tracey, Jon's wife of 10 years, says Jon's legions of devoted fans would be surprised to see what he's like at home. "He never talks about politics or world events," she says. "I forget how smart he is until I see him on television."
