I've joked about the toilet seat needed to be left up for years. You've got my vote.
The balance of power in the house has been mostly women for most of my life. They can say what they want, but they leave the seat more a mess than I ever have.
This isn't an isolated survey either. I worked at Wal-Mart in my youth for a few years. Part of my duties were to clean the bathrooms. The women's restroom was always disgusting. Bloody tampons scattered all about, feces on the walls, clogged sinks, multiple stopped up toilets. They would continue to use a clogged up toilet instead of waiting for a working one. There was a good mix of that most nights. Occasionally you'd have a clogged toilet in the men's room that would be about it.
You'd have the signs on the door, the cart blocking the door and you'd be in there cleaning and women would walk right in anyway. Most men would wait. What were we talking about again? Oh yeah, traumatic events that changed the way we see women.
