In honor of Sesame Street’s 50th anniversary, the muppets swung by NPR’s headquarters for a performance in their Tiny Desk series.

All of your favourite characters appear in the 15-minute video. Elmo, Cookie Monster, Rosita, Abby Cadabby, Big Bird, Bert and Ernie and more kick off the concert with the Sesame Street theme song.

Watch below and have your day made by the muppets.
