A man walks into a bar and sees a sign that reads, "Free drinks for a year to anyone who can make our horse laugh."
So the man walks up to the bartender and says, "I'll give it a shot."
He walks over to the horse and whispers something in its ear. The horse starts laughing uncontrollably, rolling around on the ground.
The bartender is amazed and honors his word, giving the man free drinks for a year.
A year goes by and the man comes back to the bar. The bartender asks him, "So, how did you make our horse laugh?"
The man chuckles and says, "Well, the first time I told him my salary, and this time I told him how much I paid for that free year of drinks!"
