I’m guessing it was from about 15 years ago. I think it was for a German company, and it was touting the idea that Germans are very precise while making fun of the idea that they are very rigid.
It was set in a lab-like environment. The test subject was lying on a table, and you could just see the bottoms of his feet. His toes were pointing straight up. The tester barked something like “Commence relaxation!,” and the test subject’s toes swung out to the sides a little.
I’m sure I have some of that wrong, but it was really funny. I’d love to find it on Youtube or something, but my searches have failed.
Thanks!
