A man walks into a bar and sees a sign that says, "Free drinks for the person who can make my horse laugh." Intrigued, the man asks the bartender about the challenge.
The bartender explains that his horse is a very serious animal and has never been known to laugh. The man decides to give it a try and walks over to the horse's stall.
He whispers something in the horse's ear and the horse starts to chuckle. The man is amazed and goes back to the bartender to claim his free drinks.
The bartender is astounded and asks the man what he said to make the horse laugh. The man replies, "I just told him that I have a bigger carrot than he does!"
