Lateral thinking puzzles withhold a frame rather than a fact. Everything you need is stated; what is missing is the assumption you brought with you.
The bartender with the gun is the cleanest example. Read literally it is menacing; read correctly it is medical. Nothing was concealed except your own reading of the situation — which is why the reveal lands rather than irritates. The surgeon riddle works the same way, and has aged into a genuinely interesting artefact of how assumptions shift over time.
Every question below shows all four options, the keyed answer, and the one-line explanation. If you want to turn these into video, the OmniFrame Quiz Studio is free and this pack is built in.
