The goofy brainchild of professional juggler Thomas John, "The Lady on the Wall" turns the dry bones, childhood mystery of the fall of Humpty Dumpty into a convincingly hard-boiled puppet noir, where all the puppets are eggs and almost all of them come to a rotten end. John's deadpan, pun-filled narration and his deft physical manipulation of the principal players make "Lady" the best-laid plot starring a farm-fresh, extra-large dozen in the Bay. Performance runs are sporadic but well worth the watching and waiting. You can also catch John performing his combination clowning-and-juggling shows on the Center Stage at Fisherman's Wharf, and root for him as a final contestant on America's Got Talent. Plus he plays the glockenspiel? Pretty crackin', if you ask us.
