Jimmy Fallon has secretly photobombed several tourist photos with other celebrities like Jon Hamm, but yesterday he changed it up on The Tonight Show. Instead of tourists, he had kids; and instead of human celebrities, he used some of Sesame Street’s biggest names. What we got is some of the most awwwdorable photobombs you will ever see. Not only that, the kids’ reactions were priceless when they realized that Elmo and Big Bird were behind them! Too cute!
