Joanie Cunningham

Also, in early seasons, Joanie is a member of a girl scout-type organization called the "Junior Chipmunks".As she grows older, Joanie becomes best friends with the promiscuous Jenny Piccalo, who is only referred to but not revealed onscreen until Season 8.One such notable case occurs in Season 11, when Joanie takes a teaching job at the high school where Fonzie and Roger are faculty members.Also in Season 4; Fonzie, Richie, Potsie, Ralph, and Carmine Ragusa (from Laverne & Shirley) defend Joanie's honor against a troublesome gang called the Red Devils (see "Joanie's Weird Boyfriend" from that season).However, Joanie eventually accepts a date with Chachi, making him so overwhelmed with excitement that he inadvertently sets fire to Arnold's (see "Hot Stuff" from Season 7).
