Which means the time is ripe for the ghost of Jon Stewart to stop haunting the halls of the show's New York City studio and finally drop by as a guest.
His appearance on last night's episode was a lovely affair, as Noah handled the drop-in with aplomb. He and Stewart launched into a bunch of bits—about whether the grizzled, salt-and-pepper-bearded former host was lost, and nodding to the Conan O'Brien/Jay Leno beef about late-night hosts taking their shows back.
But Stewart wasn't just there to wish the new host well or satiate his craving for attention on TV. He actually had an important issue to discuss. Stewart has long been a vocal supporter of providing medical care to 9/11 first responders.
