A man walks into a bar and sees a sign that reads, "Free drinks for life if you can make the horse laugh." The man, intrigued by the challenge, asks the bartender about the sign.
The bartender explains that the horse in the corner has never laughed before and if anyone can make him laugh, they will receive free drinks for life. The man thinks for a moment and decides to give it a try.
He walks over to the horse and whispers something in its ear. The horse immediately bursts out laughing, snorting and neighing with joy. The man returns to the bartender, who is shocked and asks, "What did you say to make the horse laugh?"
The man replies, "I told him I have a bigger carrot than he does."
