A ninety year old man lived in a rest home and got a weekend pass. He stopped in his favorite bar and sat at the end and ordered a drink. He noticed a seventy year old woman at the other end of the bar and he told the bartender to buy the lovely young lady a drink. As the evening progressed, the old man joined the lady and they went to her apartment, where they got it on.
Four days later, the old man noticed that he was developing a drip, and he headed for the rest home doctor. After careful examination the doctor asked the old man if he had engaged in sex recently.
The old man said, "Sure!"
The doctor asked if he could remember who the woman was and where she lived.
"Sure, why?"
"Well you'd better get over there, you're about to cum!"
