Martin Scorsese's Sesamean streets

It's difficult to read Muppets' lips considering they don't have any -- but, in this trailer, the colorful puppets spice up their dialogue and finally jumpstart immobile careers constricted by Children's Television Workshop standards. Leave it to the director of "Goodfellas" and "Taxi Driver" to squeeze Oscar-worthy performances out of these lipless Muppets. (And credit the real directors, profiled here, for their viral creation.)
