I was standing at the bar when a girl came up to me. "Fancy buying me a drink?" She said, "Sure," I replied. "If you let me choose." "Okay," she grinned. "But how will you know what I want?" "Well, it's kind of a talent," I smiled. "All I do is look a girl up and down and I know exactly what drink suits her best." "Okay," she giggled. "You can choose for me." So I turned to the barman and said, "Diet coke, mate."
