Here is a quote from Wikipedia, about Fonzie. I don't know how I stumbled upon it but here it is:

"Originally, according to ABC, Fonzie was supposed to wear sweaters, except when he was around his motorcycle. So, the producers of Happy Days put Fonzie around his motorcycle all the time so that he could wear the leather jacket all the time."

Why couldn't he just wear the jacket all the time? Is there a law that you can only wear a leather jacket if you are with a motorcycle? I haven't seen the show, but is Fonzie ever in a house? What do they do then, have him park his motorcycle in the living room???

So, you can vote. Who is the idiot here, the producers, the writers, or the person who wrote this on Wikipedia.
