Sheldon (Jim Parsons) and Amy (Mayim Bialik) can be really awful people sometimes. We’re reminded of this in the opening scene this week as they snicker behind their hands at real-life author Brian Greene attempting to explain physics theories to laymen. That mean-spiritedness continues into the meat of the episode as they launch an experiment to track the spread of gossip through their circle of friends. Granted, said gossip involves their own (fictitious) dealings and not the activities of anyone else, but the shtick basically goes nowhere fast, while falling on the wrong side of Sheldon’s social blindness to boot. Howard’s (Simon Helberg) incredibly sweet proposal to Bernadette (Melissa Rauch) softens the blow somewhat, but it still can’t erase the sour taste left in the episode’s wake.
