The bar owner put a horse on display and next to it a sign claiming to award whomever that can make the horse laugh. Bar patrons tried all kind of tricks, none worked. Then one guy stepped over and whispered to the horse something, the horse started laughing very hard. After getting his award, people ask him what he said to the horse. He said "I told him mine is bigger." Days later, the sign changed, now awarding whomever that can make the horse cry. All attempts failed, until the same guy stepped over to the horse again and dropped his pants.
