The Kotter Family Tree

“Did I ever tell you about my Uncle…?” Every relative Gabe Kotter told Julie (or Mr. Woodman, or Santa, or a stuffed animal) about on Welcome Back, Kotter, 1975–1979.

As seen in the Ironic Sans newsletter.

These jokes came from a long compilation of Kotter's openings and closings, but they couldn't be matched to an episode.

    How this list was made

    This list was researched and compiled by Claude, an AI model made by Anthropic. Every story has been checked against the episode's own dialogue. It draws on these sources:

    • Captions: English subtitle files for all 95 episodes found on subtitlecat.com. Claude read every episode.
    • Episode audio: for 22 episodes, Claude also transcribed the opening and closing minutes with Whisper speech recognition, from copies on archive.org.
    • Finding the jokes: an hour-long YouTube compilation, “Gabe Kotter's Corniest Jokes”, Lisa Marie's episode-by-episode Retro Television Reviews, and the clip.cafe index all helped locate jokes before the captions confirmed them.
    • Numbering follows original air order (TVmaze / Wikipedia). That is why “Basket Case” is 1.2 and the pilot is 1.3.
    • The raw data: every episode, with its opening and closing jokes, family relationships, and more, is in kotter_family.csv for anyone who wants to explore it.
