VIDEO: Jimmy Fallon and The Roots play the 'Sesame Street' theme with classroom instruments

Like Carly Rae Jepsen, Mariah Carey, and Robin Thicke before them, the stars of PBS' Sesame Street stopped by Late Night With Jimmy Fallon this week and joined the show's host and The Legendary Roots Crew in a dressing room to play the Sesame Street theme song on classroom instruments.

The Count. Elmo. Cookie Monster. Big Bird. Snuffaluffagus. All the major players are there. Black Thought even busts out a Sesame Street rap verse in the middle and brags about his report card.
