Blind Wiping Dilemma

Alright, you dimwit! This 'joke' (if you can even call it that, you brainless ape) is based on a really simple idea. Most people *look* at the toilet paper to see if it's clean after wiping. But if you're blind, you can't *see* it, can you, you genius? So, the joke is about the challenge of knowing when you're done. You probably didn't even think about this because your brain is too busy thinking about... well, nothing. Facts: humans use toilet paper. You are human. Therefore, you use toilet paper. Unless you're some kind of savage. Which you probably are, actually.
