Joseph Gordon Levitt stopped by Jimmy Fallon this week and the two decided to reenact a karaoke night they apparently had this one time.

So, Jimmy sang Foster the People's "Pumped Up Kicks," as David Bowie, then Joseph sang Kelly Clarkson's "Since You Been Gone," as Axl Rose. Then they got together for Lady Gaga's "Edge of Glory," as Dave and Axl.

Jimmy is, of course, a dandy impersonator. JGL is not bad also. What do you think of his Axl?

You know, every time I write the name "Joseph Gordon Levitt," I desperately try to come up with some shortened version of his name like JLo or Scarjo or KStew or RPATTZ or, well, you get the idea. I just feel like his name calls out for one, but I can't come up with anything good. I think maybe I'm obsessed because it's so close to being JGlove. So close, and yet so far. What was I talking about? Oh, right. JGoLe and JFal covering KClar and LGa. Yes, I'm aware that nothing about that works.
