This is disgusting, my apologies up front. I was told as a kid that to conserve rations whilst at war, soldiers would only ever wipe their bums with one piece of loo paper.
I was told that they'd tear a small hole in the centre of one piece, put their finger through the hole, wipe up all the mess with the finger and then wipe their finger with the remainder of the paper. I believed this well into my teens and shuddered at the thought of joining the army.
