There was an old man in a nursing home who always fell out of his wheelchair.
Finally, the nurses decided to do something about it, so they appointed a nurse to watch him all the time.
He started to lean forward so the nurse stuck a pillow in front of him. Then he started to lean backward so she stuck a pillow behind him. Then he started to lean to the left so she stuck a pillow to the left of him. Then he leaned to the right and she stuck a pillow to the right of him.
Later on that day, his son came to visit him. ”Dad, why do you have all those pillows around you”?
”Well, the nurses around here won’t let me fart!“
