VIDEO: Jimmy Fallon lip sync battles Paul Rudd

Jimmy Fallon has taken over The Tonight Show and turned it into one big celebrity cocktail party. He's got Bradley Cooper playing charades and Will Smith dancing to the hip hop that the kids are listening to, these days. And then, last night, Fallon hosted funny man Paul Rudd and they had themselves a little lip sync battle.

In case you're not familiar, the lip sync battle is one of Fallon's favorite bits to use when famous friends stop by the show. It started with The Office's Jon Krasinski, back in the day, but was cemented as an instant classic when Joseph Gordon-Levitt stopped by in his crushed red velvet blazer and crooned his way into our hearts with a magical rendition of Elton John's "Tiny Dancer."

Last night, Rudd gave Fallon a run for his money, covering a Tina Turner jam and closing out the show with Queen's "Don't Stop Me Now." Fallon tried to keep pace with an energetic performance of "Jukebox Hero," but ultimately had to concede.

The new Tonight Show is the best Tonight Show. Well, at least it's more entertaining that whatever Leno was bringing to the table.
