I'm always secretly tickled by the signs they hang up in ladies rooms that ask you not to flush certain things down the potty.
Sometimes they're very direct: "Do not flush feminine hygiene products down the toilet."
Sometimes they're kind of coy: "Please be gentle on our plumbing. It was installed before the invention of disposable feminine hygiene products."
Sometimes they're downright scary: " Do NOT flush ANYTHING besides human waste and toilet paper in this toilet. IT WILL OVERFLOW!!"
And sometimes, they're just amusing:
