A man was walking down the street when he saw a sign in the window of a bar that read "If you can make my horse laugh i will give you $1000."

The man walks into the bar and tells the bartender that he can make his horse laugh. The bartender gives him the go ahead, so he walks over to the horse and whispers into his ear. The horse then falls on the floor laughing. He collect his money and leaves.

A next day, the man walks past the same bar and see a sign in the window that read "If you can make my horse cry I will pay you $1000." The man walks in, the bartender gives him the go ahead, so he whispers into the horses ear again and the horse starts crying.

The bartender says to the man "Before i pay you, you have to tell me what you said to the horse."

The man replies, "To make him laugh, I told him that my cock was bigger than his. To make him cry, I showed him."
