When I was a teenager, I had a watch with an IR blaster and a few basic buttons (power, volume) built into it. I forget exactly how it worked; I think you would press the button you wanted and it would send out a bunch of common codes to control any nearby TV. Its intended use case was to do what the post describes, but more discreetly than pulling out a TV remote. I never got the chance to use it to that end, or maybe I wasn’t brave enough to try, but I loved the idea.

Had a similar Casio. There’s still mobile phones with IR blasters like the Galaxy Note 3, used that to change channels in a dentist’s waiting room.
Many chinese phones still have these built in
