Imagine you are in 30 Rock, you are taking the elevator, all of a sudden the elevator doors open up, and Paul McCartney is standing there. What would you do?
Several visitors of the NBC building did not have to imagine (I know that is a John Lennon song) that because that is what happened. Jimmy Fallon decided to prank them with the legendary Beatles singer, and they loved it. How could they not? Who doesn’t love Macca?
BTW I love that the lift people gave out a small scream when they saw the Tonight Show host, and a much larger one when they saw McCartney. Granted, they would expect to see Fallon, that other guy not so much.
