Jonah Hill is one of the very few SNL hosts with a reoccurring character. And what a character it is. Hill has played Adam Grossman, the 6-year-old who acts like he's a 70-year-old insult comedian, three times, including when he hosted this past season. Last night on Late Night With Seth Meyers, Hill told the story of creating the character. He also said that one time he had to stand up to Lorne Michaels about him, as Michaels wanted the character to age each time. "I'm 6!" Hill retorted.
