In Happy Days Richie Fights Back which was one of my favorite episode, which deals with today’s problems and important issues pertaining to the effects of bullying, where Fonzie was giving Richie tips on how to stand up to bullies, the episode where Ralph was fighting in the boxing ring, knowing that his girl friend Kitty was at ring side, and showing himself, that he wasn’t afraid of her ex boyfriend who wanted to pound Ralph’s head in, but Ralphie boy held his own. Two important episodes about bullying who can forgot Joanne boy friend who was being bullied, but he fought back, I think that was the episode which I forgot the title where Joanne was dancing with her father the late Mr. C at Arnolds where the band was singing put your head on my shoulders. Three important episodes pertaining to bullying. Oh I almost forgot the episode where Chachi wanted to join Fonzie old gang the falcons where Richie himself stood up to the Fonz

I always have liked "Fonzie meets Kat" where he runs into an old enemy named Ricco. but he deals with him without throwing a punch. all he does is blow in Ricco's ear and he falls off the table. of cours Katmandu helps by throwing her legs around. come to think of it I don't remember a show where Fonzie threw a punch at anybody but found other ways to be tough.

If I remember correctly, he did punch someone in defense of Chachi in "Glove Story."

I do remember that Fonzie kicked someone in "Joanie's Weird Boyfriend" But never saw "Glove Story" And don't remember him punching in any other episode.
