While in Japan, the TVs would often turn on the moment you entered the room. This was fine, as I would mute them or turn them off. At one hotel, I managed to bug one out such that volume didn't work anymore. No worries, I'll just turn it off. Except when I went to turn it off, it crashed the TV app and it automatically restarted. All the wires were integrated so they couldn't be tampered with and the unit had no real buttons. I thought I was going to have to sleep with the same four very excitable adverts on rotation blasting into my ears!

Mercifully, pressing the TV Source button triggered a different app that didn't crash when I pressed the off button, and in what must be the software engineering achievement of the decade, the off button turned off the screen.
