In the fifth installment of Jimmy Fallon's "History of Rap" (and his first installment as host of the Tonight Show), Fallon closed his first week strong, especially after last night's Michelle Obama kale situation. Along with Justin Timberlake, Fallon tackled some of rap's finest, including Kanye West, The Beastie Boys, and that "hotstepper" guy.

Toot too, beep beep, etc. Alright Jimmy, we get it. You're younger than Jay Leno. You're funnier than Jay Leno. You're a much better dancer. And you can definitely sing. You can stop showing off now.

Jimmy Fallon opened his first monologue of The Tonight Show Monday night with one promise: "I'm Jimmy Fallon and I'll be your host… for now." He then thanked all the hosts who have come before him, including "Jay Leno, Conan O'Brien and Jay Leno."

Jimmy Fallon will take over as host of The Tonight Show Monday night, but we should always remember that in 1998, he was just a young 24-year-old trying out for Saturday Night Live and making Lorne Michaels laugh with his Adam Sandler impersonations.

When the Tonight Show moves from Burbank to New York City next month as new host Jimmy Fallon takes over, NBCUniversal will lay off all of the show's 164 employees.

In an awkward interview Monday with Matt Lauer on NBC's Today, Jay Leno and Jimmy Fallon discussed Fallon's February transition into Leno's Tonight Show slot. The two comedians even managed to make some "jokes" that were "funny," if uncomfortable, forced humor is your thing.

In an interview set to air Sunday on CBS' 60 Minutes, Jay Leno finally opens up about his first Tonight Show ouster in 2009: "I was blindsided," admits the twice-removed NBC host.
