Heeerre's Jimmy! Jimmy Fallon signed off from Late Night on Friday, Feb. 7 with a little help from his friends -- The Muppets, of course. The host ended his 5-year run on the program by belting out The Band's "The Weight" before walking into his new Tonight Show studio.

In the sweet performance, Fallon played at the piano while the muppets -- including Kermit the Frog, Little Miss Piggy, and Gonzo -- sang into their microphones. Fallon, 39, also kicked off the show singing "On a Night Like This" with his house band The Roots and Buckwheat Zydeco.

Earlier in the show, Fallon shared highlights with the audience from over the years, and calculated that he's made over 10,000 monologue jokes in the show's 969 episodes. 

"I'll especially miss the battle for late night ratings with my fierce rivals," he said of his now previous 12:35 a.m. time slot. "Craig Ferguson and a veggie chopper infomercial." Fallon will be replacing Jay Leno on The Tonight Show beginning Feb. 17 starting at 11:30 p.m. Leno, 63, meanwhile, wrapped up his stint on the legendary program after 22 years on Feb. 6.

"I want to thank the fans. I can't believe it," Fallon said of leaving Late Night. "This didn't exist five years ago. There was no such thing as this show five years ago. Isn't that crazy to even believe that? It means the world to me. You make me so happy. Thank you so much."
