“2-3 squares is enough for a wipe”

Hi Paul. We need to talk. Your friends don’t want to say anything to you, but you really need to know this. Your ass stinks. Bad. When you get up from a chair, there’s a little whiff of shit in the air. When you’re getting off a plane or train or bus, and your ass is near people’s heads, they’re throwing up a little in their mouths. And you underwear has more skidmarks in it than the racetrack at the Indy500.

2-3 squares is definitely NOT enough for a wipe. And one wipe is seldom enough. The correct algorithm is:

do {
grab(wad_of_paper);
crack.swipeThrough;
color=inspect(wad_of_paper);
} while color == BROWN;
