Well it all depends on the thickness of the paper and whether or not you fold it. If I've got some good TP I just need two and I fold because my wiping precision is out of this world. But if it's thinner stuff, well, as much as it needs not to tear.

I'm scared of cleaning glass objects. I don't really know if that's irrational. I had a friend growing up who was legitimately terrified of bananas, though. His brother told me that once and I didn't believe him, so the next time I saw him I threw a banana at him. He screamed, fell off the couch, and didn't talk to me for a week.

I guess if I had to ask an idle question it would be how many hours do you think you've slept in your life. It takes some thinking and some math but I think that's why it's fun. It can probably really make people question their math skills and/or the reality of how much time they've spent in bed.
