The monologue did not exactly get the show off to a good start. And how did Jimmy Fallon not even know what the dougie was? If you are going to make a joke about it and then start dancing you should probably have an idea of what it is. I mean, common sense would pretty much indicate that.
We also had the second episode of Jersey Floor, Late Night with Jimmy Fallon's parody of the (for some bizarre reason) popular show on MTV Jersey Shore. It was not really funny, definitely not like his other parody shows, but I guess this probably draws more interest than those parodies do so it will probably continue for the foreseeable future I am guessing.
