A man walks into a bar and orders a beer. As he's sipping his drink, he notices a sign behind the bar that says, "If you can make my horse laugh, you get a free drink."
The man thinks this is a strange challenge, but he's feeling confident and decides to give it a shot. He asks the bartender if he can try to make the horse laugh.
The bartender agrees and brings the man over to the horse. The man whispers something into the horse's ear and, to his surprise, the horse starts laughing uncontrollably.
The bartender is shocked and asks the man how he managed to make the horse laugh. The man replies, "Well, I just told him that my ex-wife is going to remarry next week."
The bartender chuckles and gives the man a free drink. Emboldened by his success, the man decides to try again. He asks the bartender if he can make the horse cry this time.
The bartender agrees and brings the man back to the horse. The man whispers something into the horse's ear and, just like that, the horse bursts into tears.
The bartender is even more amazed this time and asks the man how he managed to make the horse cry. The man replies, "I just told him that I sold him to my ex-wife."
The bartender bursts out laughing and gives the man another free drink. The man is on a roll now and decides to try one more time. He asks the bartender if he can make the horse sing this time.
The bartender is skeptical but agrees to let the man try. The man leans in and whispers something into the horse's ear, but this time, nothing happens. The horse just stands there looking confused.
The bartender shakes his head and says, "Well, I guess you can't win them all."
The man replies, "Oh, I think I did. I just told him that I can't believe he still falls for this silly trick!"
