Jimmy Fallon, since taking over Late Night, has consistently shown off his nerdy roots and love for pop culture, as well as his willingness to do things that are just plain goofy fun. Luckily, his move to 11:30 and The Tonight Show didn't change that at all.
Case in point: when having Paul Reubens on the show Wednesday night, he had him do something a little fun: some voiceover work for Avengers: Age of Ultron. Using a clip of the first trailer for the film, Fallon had Reubens re-dub some of the dialogue as his famous character Pee Wee Herman. It's a gag that Jimmy has done himself (he's a talented imitation artist), made even more fun by the original. Check out the goofy video below.
