The wife asked how big my pisses are so I used the measuring jug to check. Now we both know my bladder volume. She didn't accept that I could just put the jug in the dishwasher. Had to buy a new one and took the washed one to a local charity shop.
@fesshole I can imagine that question, over a slow Sunday breakfast:
"Here's your eggs, sweetheart. Pass the salt, and how much do you pee?"
