A now deceased female friend of mine had a glass eye. One evening in our local club, my mate Tony got up to go to the loo and asked her to keep an eye on his pint. Josie, being the character she was, took out her glass eye and put it in his drink. When he came back, he saw the eye and laughed. Josie was just about to retrieve the eye when he said, "Don't be putting your fingers in my beer, i don't know where they've been." So saying, he then raised his glass to his lips and carefully drained his glass until only her eye was left, staring up at him from the bottom. He then held the glass out for her to retrieve the eye before going to the bar for another drink amid the ensuing laughter which didn't half irk the bingo players in the room.
