A man walks into a bar and orders a beer. As he's sipping his drink, he notices a small jar on the counter with a sign that reads, "If you can make the horse in the back laugh, you win $100."
Curious, the man asks the bartender about the challenge. The bartender explains that the horse in the back never laughs and no one has ever been able to make it crack a smile.
Determined to win the cash, the man walks over to the horse and whispers something in its ear. The horse immediately bursts out laughing, rolling on the floor and pounding its hooves.
The man collects his $100 and the bartender asks him, "What did you say to make the horse laugh?"
The man replies, "I told him I have a bigger carrot than he does."
