Jimmy Fallon is fucking embarrassing to watch. I cringed watching that stupid show (Except the Sandra Bullock thing, that did get a snigger) and both the Batman Begins and Revenge of the Sith spoofs were abysmal... It was so embarrassing to watch. They just felt so forced (No pun intended) to try and fit into the scene... In my opinion (Aside from Jimy Fallon being the least funny man on the planet... Who according to those he blows (Or "in the know") should be hosting a live show and making shockingly bad movies with loud, fat, generic black women and charisma-less Brazillian supermodels.
Remember when Billy Crystal first started doing that at the Oscars? It was funny because it typically consisted of a tiny fragment of one of the films that fitted into a nice joke and then all mixed together for an overview of the year's movies. The two spoofs at the MTV awards were dragged out and went on... It was like flogging a dead horse which is why it was so embarrassing.
