I was predisposed to like the show when it came out but after a season or so of watching it casually I stopped because a lot of the humor was played to an audience that was, frankly, dumber than me, and they dumbed down the characters too. But the show did have its moments. Checking out a fun blog by an Aussie submissive (an O/p relationship as she describes it, i.e., Owner/property) I found a link to a Youtube clip of Sheldon doing a little operant conditioning, or as it might better be described, secret slave training, of Penny.
