The final Sherlock of the season (and perhaps for the next couple of years) ran on PBS Sunday night. If you’re already feeling the withdrawals, maybe this clip can help tide you over.

Benedict Cumberbatch makes an appearance on Sesame Street, meeting his Muppet arch-nemesis Murry-arty, who refuses to believe that Benedict is an actor, not a genius detective. When Murry-arty poses a stumper of a mystery, Benedict calls upon a friend (no, not Watson).

Thanks to Indiewire for the head-up on the clip, currently posted on YouTube.
