The week-long Bruce Springsteen tribute on Late Night With Jimmy Fallon closed out Friday night with Fallon and Springsteen covering one of the most important artists in the American songbook: LMFAO. Duh.

Fallon donned his Neil Young guise and Bruce Springsteen got in character as a very rigid Born in the USA-era version of himself, cutoff jean jacket, bandanna and all. The performance is pretty funny, and it sounds like they get booed at the end, which is even funnier. Watch the performance below.

ALSO, the Boss' new album Wrecking Ball drops tomorrow, but you can stream it now over at the Boss' website. Tell us what you think in the comments below.
