Oscar winner Ben Affleck has been tasked with hosting the season finale of Saturday Night Live this weekend, and he and Bill Hader are giving us a little taste of what's to come. What might that be? Affleck impersonating Hader ("Hi, my name is Bill and I like it funky and sweet!") and a reasonable amount of Argo jokes. I'm excited to see Affleck host, but these promos feel really bittersweet given this week's news that Hader is leaving SNL after this season. More reason to tune in this weekend, I suppose.
