Good live television looks easy, but that's only because there are hundreds of people working hard behind the scenes to pull it off. Case in point: NBC's venerable sketch comedy institution, "Saturday Night Live". 

The clip above comes from SNL's Christmas episode featuring Casey Affleck and musical guest Chance The Rapper. Studio 8H is small enough that the set for the cold open - the sketch that opens the show, pre-credits - is right where the guest has to give their monologue. Watch as the SNL crew tears it all down in one minute and forty seconds.
