Continuing the tradition of celebrity cameos*, PBS just released this clip featuring Benedict Cumberbatch of 'Sherlock' fame. In the bit, Murray —  known here as Murray-arty for the purposes of maximum 'Sherlock' puns — seems to have Cumberbatch confused with his more famous BBC alter-ego. A distinction that can be lost on Muppets and fans alike.  Despite not being the World's Greatest Detective Batman Sherlock Holmes in real life, Cumberbatch sets out to solve the brain-bending puzzle put forth by Murray-arty. Can he figure it out in time?
