“Are you ready for my brain-bending challenge, Benedict Sherlock?” This cute Muppet, on PBS' beloved “Sesame Street” doesn’t seem to understand that Benedict Cumberbatch and his "Sherlock Holmes" character are not one and the same. Nevertheless, this Muppet, who calls itself Murry-arty (like Moriarty, Sherlock Holmes’ nemesis) challenges Cumberbatch to solve a mystery in the clip below. Are there more apples or oranges on the table below them? And of course the Count stops by as well, as numbers are his game. Yes, it’s for kids, but it’s pretty damn cute and perhaps the most endearing thing you’ll see online today. Learn to count with one of our most charming actors. “Sesame Street” still rules.
