Wonderful. #QAFTW

No one wants to hear this, but I was with a friend a few years ago on a flight with one of the first inflight in chair screens that had a game console.
We messed around and realized the UI looked familiar. We up arrowed a bit (or down), overrode the game selection and discovered we were in the AC system for the plane. All connected.
We decided not to go elsewhere, in case we ended up going nowhere.
