I once had my players come across a puzzle consisting of a gap too long and wide to jump across, with the express intent of having them stop to investigate some runes etched into the ground and realize the way across was to walk backwards across the gap

Instead, one of them came up with the idea to use a pair of immovable rods to climb up into the air, then tying a rope onto one of the rods and setting up a big swinging rope-type-dealy get across

He rolled good on acrobatics, so I let him do that

When all four other players got across the exact same way, I just had to laugh for a solid minute before asking them why they didn't investigate the etchings on the ground

"Oh, earlier, you had that book with the exploding glyphs in it and now we're all afraid to read things we don't understand"

I had turned all my players into superstitious aliterate acrobats
