"Live and Learn" is the second episode of the eighth season of Happy Days.
Fonzie becomes a shop teacher at Jefferson High School and has to adjust to being an authority figure. He also experiments with growing a beard.
Notes: Although out of order, this was actually the first episode produced for the season, establishing Henry Winkler (Fonzie) as the sole star with the departure of Ron Howard (Richie). Also, this episode also marks the first appearances of Denis Mandel as Eugene Belvin and Harris Kal as Bobby.
