A man walks into a bar and sees a sign that says, "Free drinks for the person who can make my horse laugh."
The man thinks to himself, "I can do that!" So he walks up to the bartender and asks, "What's the deal with the horse?"
The bartender explains that the horse hasn't laughed in years and anyone who can make the horse laugh will win free drinks for the night.
The man thinks for a moment and then says, "I think I can do it. Just give me a minute."
He walks over to the horse and whispers something in its ear. The horse starts laughing hysterically, snorting and rolling on the ground.
The bartender is amazed and asks the man, "What did you say to the horse to make it laugh like that?"
The man replies, "I told him that I have a bigger carrot than he does."
