A man walked into a bar and saw a sign that read, "Free drinks for anyone who can make our horse laugh."
The man, intrigued by the challenge, asked the bartender what he had to do to make the horse laugh. The bartender replied, "Well, we've had this horse for years and no one has ever been able to get him to laugh, so if you can do it, you get free drinks all night."
The man thought for a moment and then said, "I think I can do it, but I'll need a few minutes alone with the horse."
The bartender agreed and led the man out to the stable where the horse was kept. The man entered the stable and closed the door behind him. For a few minutes, the bartender and the other patrons in the bar heard strange noises coming from the stable – giggling, snorting, and even what sounded like the horse chuckling.
Finally, the man emerged from the stable with a big grin on his face. The bartender asked, "What did you do to make the horse laugh?"
The man replied, "Well, I told him a joke about a chicken who crossed the road."
The bartender was puzzled and asked, "But how did that make the horse laugh?"
The man shrugged and said, "I don't know, but he sure thought it was hilarious. Maybe he's just a sucker for poultry humor!"
And true to his word, the man enjoyed free drinks all night long, thanks to his unlikely ability to make a horse laugh.
