| On and Off|
| In a three-part bit, Fonzie demonstrates "on" and "off" by hitting a jukebox (which plays "Exit").
|Fonzie talks about the letter A, which he pronounces as his trademarked "Aaaayyyy".|
| Same as Yours|
|Fonzie points out some parts of his anatomy such as his hands, and then tells the viewers that they are the same as the viewers' body parts.|
|Fonzie walks out of the "Guys" room, addresses the audience, says "W", thinks of something, and walks back where he came from.|
|Brushing Teeth|| Richie Cunningham sees Fonzie brushing his teeth, even though he hadn't eaten anything. Fonzie explains to Richie the importance of dental care, and then gives Richie a toothbrush of his own.
|C||C for Richie Cunningham. Since Fonzie often referred to the patriarch of the Cunningham family as "Mr. C", Fonz explains the purpose of capitalization, or "C" representing "Cunningham".|
