- Description: Every relative that Gabe Kotter told a story about on Welcome Back, Kotter
- Author: David Friedman

Way back in 2007, I wrote [a blog post](https://www.ironicsans.com/2007/03/idea%5Fthe%5Fkotter%5Ffamily%5Ftree.html?ref=ironicsans.ghost.io) about wanting to assemble a Kotter Family Tree based on the stories told in the TV show *Welcome Back, Kotter*:

> Nearly every episode of the 1970s sitcom *Welcome Back, Kotter* began or ended (sometimes both) with the main character Gabe Kotter telling a really corny joke about a family member. It usually started with him and his wife sitting around, and he asks, “Did I ever tell you about my Uncle So-and-so?” When I was a kid, I loved this show. I found it hilarious. Now, not so much. But I’d still like to see a definitive list of Kotter family members and the situations they found themselves in.

For my post, I watched a dozen or so episodes so I could give examples of the hilarious stories Kotter told about his family, like:

> **Uncle Eddie** was a thief. He used bricks to break windows of stores so he could steal precious items for his girlfriend. When she got too annoying about all the things she wanted, Eddie asked her if she thinks he’s made of bricks. (Season 3, Episode 5)

> **Uncle Julian** was raised by wild dogs. Eventually he was brought to civilization and became a mailman. He was fired for biting himself on the leg. (Season 3, Episode 24)

> **Uncle William** was a pharmacist. He was fired for trying to fit bottles into a typewriter in order to type information on the labels. (Season 3, Episode 24)

> **Uncle Milton** was a famous spiritualist who held seances every Friday night. One night Milton felt the presence of a spirit named Max who in life made a living as a waiter. Milton asked Max’s spirit to come closer to the table. Max refused, as Milton was not at one of Max’s tables. (Season 3, Episode 25)

For years, I’ve wanted to actually go through every episode of the show and index the entire family tree. But on the list of Good Uses Of My Time, that was pretty close to the bottom.

But now we have these amazing artificial intelligence machines that can do tedious work for us! And I could think of no better use of a super-intelligent computer than forcing it to fetch and analyze transcripts of 95 corny sitcom episodes from the late 1970s and assemble a searchable database of the entire Kotter Family Tree.

I know Anthropic just [updated](https://www.anthropic.com/news/2026-usage-policy-update?ref=ironicsans.ghost.io) their usage policy to prohibit “sustained and needless abusive or cruel behavior toward our models,” but I made Claude go through every single episode of *Welcome Back, Kotter* anyway.

And it [really came through](https://ironicsans.com/kotter/?ref=ironicsans.ghost.io).

It’s not just searchable. You can filter! You only want stories about uncles? You got it. You just want stories about his parents? No problem. You want to find the story you half-remember about an air hose? Use the search tool.

You prefer visualizations? We’ve got plausible visualizations.

Maybe you prefer a more traditional family tree? We’ve got that, too.

Want to know the story about Uncle Leon? Just click on his name. We’ve got pop-up info cards.

Want to read the original joke as delivered? No problem! You can read the dialogue.

It even identifies contradictions, which makes me think that maybe Mr. Kotter’s stories weren’t entirely truthful. Like, did Aunt Rose fall out of a plane, leaving behind Uncle Jack? Or did Uncle Simon die, leaving behind Aunt Rose?

One thing I didn’t do is have AI analyze the jokes for misogyny and violence towards women. But it doesn’t take AI to see that a shocking number of jokes involve one or both.

Take for example Uncle Ernie. Here’s what Gabe told his wife Julie about Uncle Ernie in episode 8 of the first season:

> GABE: You remember my Uncle Ernie?  
> JULIE:No, I don't.  
> GABE: It doesn't matter. He doesn't remember you, either. Anyway, he's gettin' married again. This is the fourth time.  
> JULIE: The fourth time? What about the other three wives?  
> GABE: First one died from eating poisoned mushrooms. Second one died from eating poisoned mushrooms.  
> JULIE: What about the third one?  
> GABE: Fractured skull.  
> JULIE: A fractured skull?  
> GABE: Mm-hmm. She wouldn't eat the poisoned mushrooms.

Oh, I get it. So he bashed her head in. Ha ha ha. I’m pretty sure that if I told my wife that joke, she would take it as a threat.

And before you ask, no, this database does not contain family members mentioned in the *Welcome Back, Kotter* comic book. I don’t consider that to be canon.

Not even the issue where Gabe goes to the Kotter Family Reunion:

At this point, you may be saying: David, this research into the Kotter Family is all well and good, but how does this help humanity? Science? Our collective culture? Well, of course, I asked myself that, too. And the answer is that I’m giving back to the world by making all this valuable raw data available as [a CSV file](http://ironicsans.com/kotter/kotter%5Ffamily.csv?ref=ironicsans.ghost.io) for future analysts to explore. Who knows what cures or new technologies may somehow result?

So now that it’s been nearly 20 years since I had the original idea, and I’ve finally been able to realize my dream, who is my favorite member of the Kotter extended family?

Well, I did enjoy discovering Gabe’s uncle who was such a sucker that anybody could sell him anything. Not because the joke about him is any good (it isn’t), but it tickled me that the uncle’s name was Uncle Harry. That’s right. His name is Harry Kotter.

Aaaaaand that’s it for another newsletter, and another amazing use case for artificial intelligence. If this doesn’t justify my $20 a month spent on AI, I don’t know what will.

Thanks as always for reading. And if you didn’t love this issue, I have just one thing to say to you:

![](https://storage.ghost.io/c/99/08/9908ec0b-b3d5-476b-bc3c-632c5b087809/content/images/2026/10/upyournose.gif)

See you next time!
