This is a video of ‘Unnecessary Invention’ inventor Matty Benedetto demonstrating his shot-pouring coat hook, which I would argue is, in fact, a very necessary invention. Granted you have to remember to replace the empty airplane bottle with a new one every day, and make sure to return the shot glass to its holder so you don’t just pour a sticky mess on the floor, but overall I see this working decently for the first day and the first day only.

Keep going for the video, which does appear to show some Fireball (aka tomorrow’s headache juice) splashing on the wall.
