A guy walked into a bar and ordered two drinks. "How about a double instead?" asked the bartender. "No. I'm drinking with my friend from Denver." So the bartender gives him the two drinks. He drinks them while alternately sipping from each glass. This goes on for a few months. A couple of times a week he comes into the bar to drink with his friend from Denver. One day he comes in and orders only one drink. "Did your friend from Denver die?" asked the bartender. "No. My doctor told me to stop drinking." APdK
