A point of randomness: Toilet paper folding is an art form in itself. One always has to know how much toilet paper is enough. Too much of it and you'll jam the system (tried and tested by yours truly). Too little of it and your fingers will most likely poke through the flimsy surface. It has to be just right. Then there is the method to your folding, especially when doing *ahem* bigger businesses. I'd reckon 6 squares of toilet paper ought to do the trick. Sufficient to prevent your fingers from poking through, and you have to fold it in a way that also protects the rest of your palm from contact with your rear end. So it has to be wide enough, yet just thick enough to prevent something nasty from happening. It'll probably aid my explanation if there were visuals, but I'll try my best to bring it across clearly. The trick to wiping your behind with only 6 squares is to fold it like it is 8 squares. So you get the girth of 8, yet the thickness of only 6. See, take a trail of 6 squares of toilet paper. People normally half the length of it every time they fold. On average, it'll take 3 folds to reach a width that's just slightly shorter than what is required for full palm protection, but thickness-wise, it'll be perfect. However, a fold less would mean a girth wider than what is necessary for full palm protection, and a thickness that would definitely lead to poke throughs. So to fold 6 squares like it is 8, the starting fold cannot half the length of the toilet paper trail. You would have to fold it to about three-quarters of the length before folding the rest of it normally. I seriously spend too much time in the toilet.
