A man walked into a bar and noticed a sign that read, "Free drinks for anyone who can make the donkey laugh." Intrigued, the man asked the bartender about the sign. The bartender explained that the donkey in the back room had been in a bad mood all day and they were looking for someone to cheer him up.
The man thought for a moment and decided to give it a try. He went into the back room and whispered something in the donkey's ear. The donkey burst out laughing, rolling on the floor with tears streaming down his face.
The bartender was amazed and gave the man a free drink as promised. As he left the bar, the man couldn't help but wonder what the donkey found so funny. Curiosity got the best of him, so he went back into the back room and asked the donkey what he had said that made him laugh so hard.
The donkey looked at him with a mischievous grin and said, "I told him I was a better comedian than you!"
