A Roman time-traveler walks into a TOTO product showcase and somehow this works as comedy. The bit isn't about making fun of bathroom tech or Japan, it's about Lucius's genuine, almost spiritual amazement at heated toilet seats and bidet functions, treated with the same reverence he'd give to discovering actual Roman engineering. It's stupid in the best way: completely committed to finding real wonder in modern plumbing, which is exactly what made the original series work.

Lucius finds himself at a presentation held by the Japanese toilet maker TOTO, where the company shows off its bathroom and toilet equipment. There he is introduced to the newest technological developments in the field. The piece is a single comedy special made as a collaboration between Thermae Romae and TOTO, built around this showcase of modern bathroom fixtures.
