It seems this week that Jimmy Fallon can do no wrong. He and Justin Timberlake teamed up to show us how ridiculous we sound when we use a billion different hashtags, he donated $10,000 to Make A Wish Foundation of Michigan because one of the Lions players did the dance from N'Sync's "Bye Bye Bye" in the endzone during Sunday's game... And now, he's recreated the theme song from "Sesame Street" along with his house band, The Roots, and the cast of "Sesame Street" themselves. It's a must see. 

They even managed to create a new verse about how Big Bird and Snuffy are best friends and Cookie Monster is notorious for taking selfies.

Mostly I love this video because Jimmy looks like he's having more fun than he's had in his entire life. Frankly, if I got to sing with the cast of "Sesame Stree", I'd be pretty stoked, too.
