Just one day after Jay Leno's exit from The Tonight Show , the esteemed host of Late Night With Jimmy Fallon farewell on Friday night. He wasn't alone, though; Fallon enlisted a little help from his friends The Muppets in saying goodbye to the show once and for all. The whole gang sang "The Weight," a 1968 classic from The Band. The performance is so cute and, frankly, a little bittersweet. I know, I know, he'll be back on NBC and hosting The Tonight Show starting Feb. 17, but it's still sad. You'll want to watch until the very end to get a peek at Fallon's next chapter!
