Jason Klamm from the Comedy on Vinyl podcast (previously) writes, "My comedy duo just set a world record with the world's smallest playable comedy album. People in A Position to Know made a custom turntable and plinth and we got it down to 1.5". It's a really dumb joke (set up on side A, punchline side B), but that was sort of the joy of having to put it together. Since Guinness doesn't want to accept a new world record by genre, they didn't include it, but there are no other contenders that any of us have been able to find."
