The beats were bumping and the rhymes flowing on Late Night With Jimmy Fallon the other night when the host featured a hip-hop version of the Sesame Street theme song.

Jimmy Fallon and The Roots were joined by Sesame Street characters Thursday to celebrate the children's show's 44th season by playing its theme song on classroom instruments, the Daily News reports.

Kicking off with a countdown from the Count, Fallon and his house band begin singing the catchy light-hearted tune alongside new pals, Elmo, Cookie Monster, Big Bird, Snuffleupagus, Grover, Murray Monster, Zoe and Abby Cadabby.

Just one minute into the performance, The Roots' Black Thought added his own spin to the song with a "Sesame Street"-inspired rap.

"OK, you heard about, through word of mouth/Big Bird is out, he's in the house," he rapped. "He's turnin' up, with Snuffleup/They're really gettin' their hustle up.”
