Does Jimmy Fallon have a particular affinity for Will Smith and family? First he sings the 'Fresh Prince of Bel-Air' theme song as Neil Young. Now he's combined his perfect impression with Willow Smith's 'Whip My Hair' tune. Whatever his reasoning, we like what we see (and hear).

On 'Late Night' (weeknights, 12:37AM ET on NBC), Fallon played acoustic guitar and intoned in Young's trademark whine, "Don't let haters keep me off my grind / Keep my head up, I know I'll be fine / Keep on fighting until I get there / When I'm down and I feel like giving up, I think again..."

Then Bruce Springsteen joined him for a somber rendition of the chorus: "I whip my hair back and forth, whip my hair back and forth / Just whip..."

Jimmy Fallon does a really good Neil Young impersonation, and last night on 'Late Night' (weeknights at 12:35AM on NBC), he did an impersonation of Young doing "Double Rainbow," a song based on the now-classic video of the guy being amazed by a double rainbow in Hawaii.

Here's the original video if you haven't seen it. Jimmy Kimmel had the guy on his show recently.

I grew up watching Johnny Carson on The Tonight Show. I saw George Carlin, Joan Rivers, and countless other comedians on the show, oftentimes my first exposure to comics I would later devote most of my adult life to covering in print (or virtual print). There is no questioning how important Carson's Tonight Show was for me.

But it was always the late night guys that got me. I loved Carson's show, but I identified much more with the sheer lunacy and sometimes brutal quality that Letterman created. And when I got to college, there was this new guy, Conan O'Brien, in Letterman's spot.

Jimmy Fallon delivered a spot-on impression of Neil Young performing General Larry Platt's 'Pants on the Ground' on 'Late Night with Jimmy Fallon.'

Fallon performed Platt's audition song from 'American Idol' word-for-word, and invoked Young's image by wearing a cowboy hat and wig, strumming a guitar and playing a harmonica on a neck holder.

Watch the video after the jump.

Jon started with some good ol' presidential humor by covering Bush's visit to Asia. The president went there to sign a nuclear cooperation (or as Bush would say it, "a nuke-ular kwap'ration") with India. America will help India build nuclear reactors if they promise to stop their children from crushing us in spelling bees. Bush also learned about Indian culture, seeing cloth made the old-fashioned way on looms, visiting farms, and facing one hell of a huge potato. "Compared to India, our potatoes are literally small potatoes!"

Well this was a pleasant surprise. After the past few mediocre episodes (save for the handful of great sketches in last week's Baldwin explosion), I wasn't expecting much from this. Sure, Jack Black is great and all, but lately I've just come to expect to be disappointed from SNL. Fortunately, the writers put together a nice set of laughs (and a couple extra guests) which is a good thing since this is the last episode we're getting until Scarlett Johansson hosts on January 14th.
