"The Cunningham Caper" is the fourteenth episode of the second season of Happy Days, also the 30th overall episode in the series. Co-written by Michael Weinberger and James Ritz, the episode, which was directed by George Tyne, premiered on ABC-TV on January 21, 1975.
Richie stays at home sick while the rest of the family take in a movie at the theatre. But then he hears noises downstairs, and finds himself face to face with a burglar, who forces him to help gather up the family's valuables.
Fonzie, Potsie, Ralph, and a burglar cause pandemonium in the Cunningham house while Richie is sick in bed with the flu.
Marion brings some green-colored jello upstairs to Richie's room, while he is sick in the bed with the Asiatic flu and he struggles to complete a jigsaw puzzle. Howard says they are supposed to go to the cinerama that night, but decides to cancel their plans. Richie plays some basketball with wrapped-up paper and a trash basket in his room. Fonzie comes through the window and brings Confidential, Police Digest, and Playboy.
Fonzie borrows Richie's car to take Yvette to the drive-in. Potsie and Ralph bring over a French sun-bathing film and Richie tries to convince the family to go the cinerama that night. Richie calls Potsie and Ralph and tells them to come over to the house and later goes downstairs and is surprised to see a burglar.
Richie and the burglar talk and then they go into the dining room to get some silverware. The burglar hides out in the closet and Richie tries to give Ralph and Potsie the film projector. Richie tries to write out "HELP" on the door and Potsie guesses "HELF". Ralph and Potsie come in and meet the burglar. Richie and company are locked in the bathroom while they decide on a way to escape. Ralph goes through a small window, but is caught when he doesn't jump out of a tree.
Their next plan is to have Potsie make up an excuse, spray the burglar with shaving cream, and then have Richie run for help. Of course, their plan fails miserably. Finally, Fonzie comes over with a $1.75 pizza and then locks the burglar in the closet with a chair.
