Mister Rogers finds Bob Trow’s dog and feeds her dog biscuits. He shows a film about two workers fixing the lines under the manhole and talks about safety measures. In the Neighborhood of Make-Believe, Bob Dog is barking at the trolley and Henrietta Pussycat is afraid Bob Dog’s teeth will bite her. Lady Aberlin shares with Henrietta her fear of scissors when she was young. Lady Aberlin tells everyone that the King Friday and Queen Sara have a good secret, but she can’t say what it is yet. Bob Dog fears the secret is to send him away for showing his teeth. Later, Mister Rogers talks about fearing teeth and scissors because we are afraid we might hurt another person.
