Joanie comes home from her date ice skating with Tommy Fletcher early because he is a goofball. Joanie goes down to Arnold's to get Richie so he can help Howard shovel snow. Potsie and the band are playing for a girl on the phone at Arnold's. Potsie says he needs a real girl to sing to. Joanie comes in, and Fonzie suggests that Potsie sing to her. Potsie sings "Put Your Head on My Shoulder" (a Paul Anka song) as he looks Joanie in the eyes. Joanie is fascinated by Potsie. Richie and Ralph want to practice next week, but Potsie says he can't because he has to sing at his cousin's wedding. Ralph calls him a nerd, but Joanie says he is not a nerd. Ralph leaves, followed by Richie, while Joanie stays behind to help Potsie. Ralph comes back (at the urging of Richie) to help Potsie put the equipment away. Richie and Joanie leave. At the house, Joanie watches a Katharine Hepburn
movie on the couch. She falls asleep and has a dream where Potsie (dressed in a white suit) is cool, Fonzie acts like a nerd, and she and Potsie are getting married. Joanie wakes up when Marion and Howard return home. Joanie asks Fonzie what he likes in women, and he tells her that mystery gets his blood up. He also tells about a secret note he once received from a girl named Vivian. Joanie tries this on Potsie. Potsie finds notes in his hamburger, coat pocket, and in a book addressed to "Dren." A note tells him to go to Arnold's, push H14 on the jukebox, turn around, and she will be there. Potsie thinks the whole thing is a joke played on him by Richie and Ralph. Joanie says that Potsie is just the opposite of a nerd and that "nerd" backwards is "Dren". Potsie lets Joanie down easily. Richie and Ralph show up to see Potsie and the mystery date while Joanie hides under one of the booth's tables. Richie knows Joanie is there because he finds her coat under one of the tables, and they leave Arnold's together. Marion and Joanie talk, and Marion gives her a jar of peanut butter.
