One day a man takes his frail, elderly mother into hospital.
"I hope the nurses treat you well, mum." he said.
After a while, the old lady slowly tilts to one side, so 2 nurses put her back up.
In half an hour, the old lady tilts to the other side, so the same nurses pick her back up again. When the woman's son comes to see how she\'s doing, he says, \"Have the nurses been treating you well?\"
"Yes," replied his mum. "But they won't let me fart!"
