Hamm left audiences stunned with his considerable comedic chops when he hosted for the first time in 2008. He's has sinced follow up two more times and has had a handful of surprise cameos.
From his unforgettable "Jon Hamm's John Ham" sketch—you know, lunch meat you eat on the toilet—to his live-action Ace in an adaptation of the iconic Ambiguously Gay Duo animated sketch, he's ingratiated himself with cast in a way few other hosts ever have.
