Pete has replaced three toilets, ripped out three sinks, and installed a deadbolt — and he still approaches every new project like a man who has never held a wrench. This is the competence paradox at its most domestic, and it lives underneath your bathroom floor in something called a wax ring that you absolutely did not know existed until right now.

Then Tommy takes Pete on a world tour of tipping culture — from Japan (embarrassing) to Egypt (hold out your hand) to Iran (bring jeans) — before landing on the one that hits closest to home: why is the airport kiosk asking how much you appreciate it? The history is darker than you’d expect. The math hack Tommy’s dad taught him is genuinely useful.

Nobody walks away with answers. Somebody walks away with five podcast dollars. It’s a good episode.
