People on r/threescompany (https://www.reddit.com/r/threescompany/comments/1q3dryy/jacks_father/) have been arguing that he resembled Larry more in terms of physical appearance and personality traits.

Dick Shawn (born Richard Schulefand in Buffalo) was great. Veteran well accomplished comedian fit the bill well. Sadly died in San Diego, CA in 1987 - Jack Trippers home town. No doubt if Dick was around today he would have been a proud zany member of Bills Mafia !

Dick Shawn was one of the most unpredictable and energetic comedy performers of the 1960s and 70s. Best remembered for his hilarious role as Lorenzo St. DuBois ("L.S.D.") in the Producers, Shawn brought a wild, improvisational style that made him a standout in film, television, and nightclub comedy.

In this episode, Chris and Gerry explore the life and career of Dick Shawn, from his early days in comedy and Broadway to his unforgettable performances in classic films. We'll look at how his unique comedic style influenced audiences and why his performances remain memorable decades later.

If you enjoy classic Hollywood, vintage comedy, and cult film history, Dick Shawn is a performer worth rediscovering.

A little bit of trivia in the episode where he appears as Jack's dad. Near the end of the episode in the Bitro's kitchen he calls Jack, John. Apparently since John was his real name it maybe was not caught by directors but its there.

That is a great catch. That could go either way. Yes he possible called him by his real name and no one caught it. Or it was intentional in the script. Many named John go by nickname Jack, (JFK, etc). So it could have been a simple playful switcheroo in script. I actually have known a few Jack's for many years and never knew there real name was John, cause no one called them John.

I don't know about now but I remember watching this episode when it aired when I was a kid. I remember i didn't like it or Dick Shawn as his dad.

I don't like this episode. But it was when the wheels were coming off and preparing for the spin off. The episodes where Jack's grandfather and dad spontaneously showing up and knowing nothing about Jack was stupid.

Jack Buck (https://en.wikipedia.org/wiki/Jack_Buck), who broadcast St. Louis Cardinals baseball games for many, many years was born, John Francis Buck. I don't know exactly how "Jack" became a nickname for the name "John", but there is some precedent, even if it was an accident and goof on Three's Company's part.
