If you didn't know, Will Ferrell and Red Hot Chili Peppers drummer Chad Smith look almost identical. Last night on The Tonight Show, Jimmy Fallon decided to bring the two together and have some fun.

Not only were the two dressed in the same clothes, but they also engaged in a drum-off that lead to a surprise performance by the band. Will even brought out his famous cowbell for the show, which is filled with plenty of hilarious moments.

Have yourself a laugh on this Friday morning, and watch the video above.
