A man walks into a bar and sees a sign that says, "Free drinks for the person who can make our donkey laugh." The man thinks he's up for the challenge and asks the bartender to point him towards the donkey.
The bartender takes him outside to a pen where a grumpy-looking donkey is munching on some hay. The man walks up to the donkey and starts telling it the funniest jokes he knows. He pulls out all the stops, telling puns, one-liners, and even some slapstick comedy.
But no matter what he does, the donkey just stares back at him with a blank expression. The man starts to get frustrated and tries even harder to make the donkey laugh, but nothing seems to work.
Finally, the man throws his hands up in defeat and turns to the bartender, saying, "I give up. This donkey is impossible to crack."
The bartender chuckles and says, "Don't feel bad, buddy. Nobody has been able to make that donkey laugh in years. But hey, at least you tried. And as promised, your drinks are on the house."
The man shrugs and takes a sip of his free drink, feeling a mix of disappointment and relief. As he walks back into the bar, he can't help but chuckle at the absurdity of the situation. And who knows, maybe one day he'll come back and give it another shot. But for now, he's content knowing that he gave it his all in the quest to make a donkey crack a smile.
