A man walks into a bar and sees a sign that says, "Free drinks for the person who can make our horse laugh."
The man thinks to himself, "I've got this," and confidently walks up to the bartender. He asks for a glass of water, takes a sip, and then whispers something into the horse's ear. The horse starts laughing uncontrollably, snorting and neighing with joy.
The bartender is amazed and hands the man a free drink. As he's enjoying his beverage, the bartender asks, "What did you say to the horse to make it laugh like that?"
The man replies, "I told him I have a bigger carrot than he does."
