Another eye joke

A traveling salesmen spent two weeks in Indianapolis on business, every night he went out and had sex with a different women. On the last night he was in the motel bar alone, the bartender asked him why he wasn't out on his last night in town. the salesmen told him he had sex for two weeks with a different women every night and had tried everything known to man. the bartender took a piece of paper and wrote down a name and address and gave to the salesmen telling him this would be different. The salesman followed the directions to the address and told the women that Joe the bartender had sent him.
The women invited the man in. The women knelt down and to the salesman surprise took out a glass eye. the women then insisted that he insert you know what in her eye socket.
At first the salesman resisted but then he did as she said.
When they were done the salesman told her that was the best sexual experience he had ever had and offered to pay the women.
She replied NO THANKS BUT THE NEXT TIME YOUR IN TOWN I'LL KEEP AN EYE OUT FOR YOU.
