A man walks into a bar and sees a sign that reads, "Free drinks for anyone who can make our horse laugh."
The man, feeling confident in his joke-telling skills, approaches the bartender and asks about the challenge. The bartender points to a slightly grumpy-looking horse in the corner of the room and says, "If you can make him laugh, you'll get free drinks all night."
The man thinks for a moment and then decides to give it a shot. He whispers something in the horse's ear, and suddenly the horse bursts out laughing uncontrollably. The man is ecstatic and the bartender is amazed.
The man enjoys his free drinks all night long, but the bartender is still curious about what the man said to make the horse laugh. Finally, he approaches the man and asks, "What did you say to that horse to make him laugh like that?"
The man smiles slyly and whispers, "I told him I was a better jockey than him."
