I don't stay up very often but when I do, it's one of the two Jimmys that I will watch. I wasn't sure if Fallon would do well as I was thinking he'd be the same format as Leno but he went in such a better direction. He's been killing it with some of the things he gets his guests to do.
From last nights' SuperBowl show.
