A man walks into a bar and sees a sign that says, "Free drinks for a year to anyone who can make our donkey laugh!" Intrigued, the man asks the bartender about the challenge.
The bartender explains that they've had the donkey for years and no one has ever been able to make it laugh. So the man decides to give it a try.
He whispers something in the donkey's ear and suddenly, the donkey starts laughing uncontrollably. The bartender is shocked and asks the man what he said to make the donkey laugh.
The man replies, "I told him that I make more money in one day than he does in a whole year!"
