Jimmy Fallon and The Roots were joined by several Muppets to sing the Sesame Street theme song.

Fallon and his house band used classroom instruments and sang along with many of the Muppets from Sesame Street, including Big Bird, Elmo, The Count and others, the Los Angeles Times reports.

The video shows everyone stuffing themselves into a small dressing room and singing towards what is made to feel like a webcam.

Black Thought from The Roots even added his own twist to the theme song by rapping a short bit.

Jimmy Fallon has been cranking out several videos of late with other big Hollywood stars. He recently performed a lip sync battle against Stephen Merchant and Joseph Gordon-Levitt. JGL won that by enthusiastically performing Nicky Minaj's "Superbass."

The Late Night comedian also recently made a video poking fun at Breaking Bad called Joking Bad, where he and his announcer sell jokes until caught by their head writer.

Fallon and Justin Timberlake also teamed up this week to make a video showing how stupid saying hashtags out loud would sound.

Doesn't the Sesame Street video just brighten your day?
