A farmer, who wasn't all that familiar with newfangled technolagy, had never went on a airplane but had to visit his sick daughter in New York city. Having to use the restroom badly, he asked the flight attendent where the bathroom is and was pointed all the way down to the back of the plane - but with a warning to not press the third button.
The farmer went in and pressed the first button. It throughly cleaned his front private. Delighted, he pushed the second button and it cleaned his rear end throughly as well. With the memory still fresh in his mind about the flight attented saying not to press the third button, curiosity got the best of him and he pressed it... and ended up in the hospital.
Next thing he remembers is waking up in the hospital, looking over at the doctor an asking "What happend?" "Well..." The doctor replied, "the third button on the plane... was a tampon remover." Ouch.
