I’ve been a bit…casual today. My work week was a bit tiring, so I’m giving the body AND brain a rest and am watching “Greatest American Hero” for the first time on the free NBC Peacock streaming service. It was created and produced by the late great Stephen Cannell, so you just know it will be entertaining! At least as entertaining as the production company sign off at the end of a Cannell show (Sit, Ubu, sit). Did he really have a dog named Ubu? Is that golden doodle hairdo natural or a perm?
