I ordered a small Klein bottle from him, and the best part wasn't even the bottle I eventually received. It was the emails he sent me as he prepared the shipment, along with photos of him wrapping the bottle, his wife's garden, the bike he rides to the post office. Second best thing was the hand-written note he included thanking me for the order. Third best thing is the bottle itself, but honestly, it's just another knick-knack on my shelf.

I had the same thought, he cherishes making you laugh and having a good and interactive experience. He has different jokes for every country.

When I received my Klein bottle, along came some papers from ACME with numbers and instructions. The delightful inside baseball cane when he had a field for "number of ingredients in Licor 43"!

Yes! I run this zero-volume business for fun ... and the joy of meeting interesting people. So your note brings a broad smile to this tired astronomer's face. Thank yoU!

Similar story. Ordered one for my wife. Also recommend watching him on YT (Numberphile).

I just bought one and he emailed within an hour and shipped within two. The photos and conversation were lovely. He's a role model.
