Well we don't have a shower, so neither of us can piss in it, but Stealthcat can strip paint at 50' when letting rip (which she does frequently and often). There have been times when I've been tempted to nail the duvet to the bedframe to save having to get the stepladder out at 3am to retrieve it from the ceiling.
She cleans the camelbak bladders, cuz I can't be arsed, but I make the coffee (on a poncy machine, which has been one of our better investments), because a) I'm better at it, b) it means she doesn't have to get up so early.
She does have a thing about clean baths, but I can't remember her ever cleaning the bog (despite the comments above) in living memory.
It's all give and take isn't it? Living with a "perfect lady" would get a little bit wearisome.
