Celebrating the 500th episode of Late Night With Jimmy Fallon last week, director Cameron Crowe discussed his new documentary Pearl Jam Twenty, due out in theaters on September 20, 2011. He also brought some goodies along with him and there’s video proof. It’s like a Pearl Jam party on my laptop!

Check out all the clips of Crowe and Pearl Jam, who performs a song, from the episode here below.

Legendary guitar virtuoso Yngwie Malmsteen joined the musical group The Roots on Thursday’s episode of Late Night With Jimmy Fallon.

The guitarist shreds his way through the entire episode, which you can watch here below.

Malmsteen was on the show promoting his latest album Relentless, which was released this past November; he’s also on the cover of this month’s Guitar Player magazine.

Just a few days ago, the announcement trailer for Uncharted 3: Drake’s Deception made its debut at the Spike TV Video Game Awards. The trailer was mostly cinematic, but did offer some very brief gameplay teases toward the end.

Thankfully for we the fans, Naughty Dog, the game studio behind the immensely popular series that includes Uncharted: Drake’s Fortune and Uncharted 2: Among Thieves, isn’t waiting around patiently to show more of their new game off. Co-presidents Evan Wells and Christophe Balestra were guest on Late Night with Jimmy Fallon recently, and they brought with them some real, solid gameplay footage to let the host try out.

We’ll still have to wait a little longer to really see how the game will look overall due to the fact that this gameplay is set inside a burning building, but it’s an intense burning building sequence and promises that the game will keep up the brilliance of the previous two installments.

Remember back in September when we told you about the Muppets and their future plans for re-taking over the world (Read: It’s Not Meat, It’s Not Puppets “¦ It’s The Muppets & They’re Coming Back Big!)? Well, they’re still going to do all of that! But as we also said, they never really left us either; those lovable Muppets love to make random TV appearances.

One of these appearances was last night on Late Night with Jimmy Fallon, where the Muppet gang joined Jimmy in singing the “12 Days of Christmas” along with The Roots. Yes, you read that correctly: The Muppets. Jimmy Fallon. “12 Days of Christmas.” The Roots. Wacky, huh? The song is typically known as one of the arduous variety, but with a little Muppet action, the simple nature of Fozzie Bear, and an appearance by Animal, this is one of the better renditions you’ll check out.

As always, click on over to the other side to check out the video, and a very Happy Holidays to all of you wonderful readers we have!

Is there anyone out there who doesn’t like Betty White?

I didn’t think so.

White made an appearance this week on Late Night With Jimmy Fallon where the 87-year-old beloved actress went up against the host in a game of Beer Pong. I suggest you take a moment to watch the clip here below; it’s funny and quite enjoyable. I think I could have watched like an hour of Betty White playing Beer Pong. And I love how the audience loved White too, screaming her name like she was a rock star. Awesome.

White was promoting her new movie The Proposal, a rom-com starring Sandra Bullock and Ryan Reynolds that I probably wouldn’t have given a second glance to had it not been for White’s role in it.
