Rogers says three stanzas of Won't You Be My Neighbor? Then he shows a box containing another box with a pushbutton. He pushes the button to play a recorded voice of someone laughing. Some people, he explains, laugh when they hear other people laughing. A phone call from Chef Brockett tells Rogers of "Gingerbread Brocketts," prompting Rogers to visit Brockett's Bakery. Sergio tells Rogers the Spanish verb for "to laugh," before Rogers sees Chef Brockett in the kitchen. The "Gingerbread Brocketts" are gingerbread cookie faces with chef hats. Chef Brockett has decorated each cookie with eyes, nose and hat, but not with a mouth. He tells Rogers that any kind of mouth can go on the cookies to match any emotion. Rogers asks Brockett decorate a laughing mouth on one cookie. After Brockett tells how to work the icing, Rogers draws one cookie with a sad and happy mouth. Brockett then does mouths with bored and surprised looks. Rogers selects the laughing cookie to his television house.

Back at the television house, Rogers says everyone is different when it comes to things like laughter. A series of strange noises outside leads Rogers to the porch, where Eric Kloss is playing the wind synthesizer. It's set to laughing first. Eric changes the tone to a fanfare, and then to other instruments. Eric's wife stops by to direct him to a class at the school.
