One day, a man walks into a bar and orders two drinks filled halfway. The next day, he orders the same thing. After a week, the bar tender asks, "Why do you always order two drinks filled halfway, when you can order one drink to the top?" The man answers, "One drink is for my friend, and one drink is for me!" So the bartender lets him order the drinks this way. After about a month, the man begins to order only one drink halfway. The bartender, worried, asks the man, "Did your friend die?" The man answers, "No, I quit drinking."
