Jon Stewart was on Late Night With Conan O'Brien last night discussing fatherhood, or, as the Daily Show host describes it, "a chance to ruin someone from scratch."

In the clip at left, Jon shows how his son, Nathan, tries to make secret plans with dad during his little sister's nap time, and explains that little Nathan is going to grow up thinking it's normal to sit with The View's Whoopi Goldberg at Knicks games.
