bidet
That is like the story about the plumber who is working in an upscale beauty parlor and asks if he can use the rest room. The operator says, "Yes, but it is a high tech toilet, so DO NOT push the red button". He goes in and sees that there is a button marked "Wash", one marked "Dry", one marked "Blower", and an unmarked red button. After using the toilet he pushes the wash button and is treated to a gentle spray, then the dry one and the warm air evaporates the water. The blower button produces a soothing feeling. Then he wonders what will happen if he presses the red button, so he pushes it. The clients in the beauty parlor suddenly hear an agonized scream from the rest room. One lady asked what happened. The attendent said, "He must have pressed the button that inserts the tampon".
