A man walks into a bar and sees a sign that says, "Free drinks for a year for anyone who can make our horse laugh." The man, feeling confident in his comedic abilities, decides to give it a shot. He walks up to the horse and whispers something in its ear. Suddenly, the horse bursts out laughing, rolling on the ground and slapping its hoof on the floor.
The bartender, amazed at the man's success, offers him free drinks for a year. As the man is enjoying his free drinks, the bartender asks him, "What did you say to the horse to make it laugh?"
The man replies, "I told him I was going to bet on him to win at the races."
