ninety year old lady joke

A ninety year old lady is on her way to the gynecologist due to a itchy rash in her puss... when she gets there the doctor checked her out and asked "when is the last time you've had sex?" the old lady tells the doctor that she is still a virgin.. he checks her out again and the doctor tells the lady "I don't really have a medical term for this, so I will be blunt...Your cherry has rotted"
