A guy walks into a bar in Louisville (KY). He orders 3 drinks but he is the only one there. The bartender wonders, but serves him his 3 drinks and says, "you don't have to order 3 drinks at a time. I'll bring them to you one at a time." The guy responds, "Well, there were 3 of us who all worked as horse trainers in the same barn, but they moved to different parts of the country and now they have their own barns.".
This went on for several months until one night the guy came in and only ordered 2 drinks. The bartender hated to say anything because he feared the worst. But he said, "I see you're only ordering 2 drinks. I hate to ask, but did something happen to one of your friends?"
