1) Negative reinforcement. As young boys, learning to potty train, we were taught to aim for the Cheerio. In adulthood, when the Cheerio is no longer present, it appears many men are choosing instead to aim for the floor tiles.
2) Sleep Deprivation. Men, too tired from watching sports and crime dramas on TV, are nodding off on the job. I personally find it amazing that more men don’t exit the washroom covered in their own urine.
3) Lack of Kegel Exercises. Fat and lazy North American men cannot adequately control their bodily functions, and end up peeing uncontrollably.
4) Territoriality. Ignorant buffoons are deciding to pee on the floor in some ill-guided attempt to mark their territory. Problem is, these are public washrooms.
