'Sesame Street' Muppets Join Jimmy Fallon for 'Tonight Show' Hashtags

You're a lucky man, Jimmy Fallon. As if having Justin Timberlake as your best friend isn't already enough, you get to hang out with Muppets too.

A few Sesame Street Muppets joined Fallon during Thursday night's episode of The Tonight Show, appearing in Fallon's weekly Hashtag sketch. Old favorites like Elmo, Cookie Monster, Grover and Big Bird were joined by characters like Abby Cadabby and Murray. (I have no idea when these two became main Sesame Street characters. What ever happened to the Two-Headed Monster?)
