A man walks into a bar and sees a sign that says, "Free drinks for a year to the person who can make our horse laugh."
So the man walks up to the bartender and asks, "What's the deal with the horse? Why does he need to laugh?"
The bartender replies, "Well, he's been really down lately and we thought a good laugh might cheer him up. But no one has been able to make him laugh yet."
The man thinks for a moment and then says, "I think I can do it. But I'll need some props." So the bartender hands him a trumpet, a rubber chicken, and a pair of clown shoes.
The man walks over to the horse and starts playing the trumpet, honking the rubber chicken, and dancing around in the clown shoes. But the horse just stares at him blankly.
Frustrated, the man goes back to the bartender and asks, "What's the deal?! Why won't the horse laugh?"
The bartender replies, "Well, you came close. But everyone knows horses don't laugh at random jokes. They only laugh at puns."
The man nods, determined to win the free drinks. He goes back to the horse and whispers in his ear, "Why did the pony go to the doctor? Because he was a little hoarse!"
And just like that, the horse bursts out laughing, tears streaming down his face. The man is declared the winner and enjoys free drinks for a whole year.
And from that day on, whenever someone asks why the horse is laughing, they say, "Because he finally heard a pun that was hoof-tastic!"
