Sherlock star Benedict Counterbatch Cumberbatch has jumped from one PBS show to another to win over an entirely different audience.

The actor appears on an upcoming episode of the children’s program Sesame Street, and Murray (who wants to be called Murray-arty, a play on the villain Moriarty) confuses him for the detective he plays on Sherlock. He asks the actor for help determining if there are more apples or oranges on the table. Despite being a wiz on screen, this task proves too difficult for Cumberbatch, so he requests the help of Count Von Count.

Sesame Street frequently welcomes celebrities to the show, and even though John Watson gets name checked in the clip above, we don’t see an appearance from Martin Freeman. Maybe next time!

The Sherlock season 3 finale aired on PBS Sunday night. Now that we’re without new episodes for a while, we compiled a list of movies you can see Cumberbatch in until season 4 begins.
