Monty Python and the Curse of the Natural One

I remember once my players spent like 15 minutes discussing how to get across a 10 foot long puddle of water in a cave.

Eventually I had to remind them that 10' isn't that far, and you can RAW jump your strength score in feet with a running start. They didn't need to build a bridge or cut into the walls. They could also just go into the water, but I understand not wanting to submerge yourself in cave water when you don't know what's down there.
