This question, asked by Jim Jefferies in his bit about guide dogs, ruined my wiping experience. When I was younger, my ass smaller and and my shits smoother, it was enough to give a single wipe and go on with my day. Then Jefferies asked the question of how blind people see the poop on the paper, and the next time I had to look at the paper and do a control wipe to see that it’s clean. But now that I’m fatter and my shits messier, I have to do like six wipes to get a clean one. Curse you Jim Jefferies.
