I disagree about the whole 'people only like it because it makes them feel intellectually superior' because its just a situational comedy, thats whats funny. Their inability to conform with certain social norms, the messes they get themselves into (Mars Rover anyone?) and the little nuances like 'KNOCK - Penny? KNOCK - Penny? KNOCK - Penny?' even when she opens the door early he cant let go of the routine lol.
