Lloyd Battista is not on of off, in my opinion.  He fills in a lot, as all of the actors did, but he has great range and when he's given the chance to shine, he takes it and runs away with it.  He's on the money is this episode, and, as heard in other episodes, has unusually good chemistry with Russell Horton.  I wish they had been in more episodes together.  The concept works better here than the actual story, but they make it work.
