Is it a fact or is it fiction that The Fonz really didn't like liver. It's causing lots of rows and we need to know.....confused

I dont remember what ep this is, but it does ring a bell.

Isn't it the episode where Richie writes an article for the newspaper or does something that creates a lot of attention, and he decides to do another article about liver but it involves revealing Fonzie's fear and dislike of liver? Did that make sense?
