Post any nicknames/names given to him by people on the show..I'll post a couple

-Fonz/The Fonz
-Fonzie
-Arthur (Mrs. C)
-Arthur Herbert Fonzarelli (Full Name)
- Clyde (name given to him by boy in episode where he loses his dog) :lol:

Skippy - his Grandma Nussbaum called him that
Mr Fonzarelli, Dean of Boys - by his students in the last seasons
Artie - he got called this by a couple of people during the series - just not very often, like in "Fearless Malph" for example

....what was it that Officer Kirk always called him, besides just "Fonzarelli", i mean - didn't he call him "greaser" or something else referring to his jacket?

Yeah I think Officer Kirk called him Greaser or something other then his first or last name. Did the gangs he was in, ever call him anything obsurd? I remember one of the members just called him Fonz but I was just wondering.

Champ-by the son of the woman he was dating on the episode "Kid Stuff (season 6).

I can't remember who said it or in what episode, but Fonzie was dismissively called "Ducktail". For his haircut. Its similar to calling him a Greaser.
