I'm usually fast asleep by the time Jimmy Fallon comes on and I'm to old to know any of the songs by LMFAO. However, this cover done by Jimmy Fallon as Neil Young, and Bruce Springsteen as himself is very, very funny! Check it out.

Jimmy Fallon nails that impersonation of Neil Young, right down to the harmonica. Bruce, not to be outdone, gives us 'passion in his pants.' Nice work gentlemen.

I'm going to ask my kids now if I can borrow the new LMFAO cd! I'll let you know if I like it!
