Horse in a Bar

A man walks into a bar. He sees a big jar of money on the bar and a horse in the corner. Naturally curious, he approaches the bartender: "Hey what's up with the money and that horse?" The bartender replies "Well whomever can make the horse laughs, wins the jar of money." The man, feeling confident decides to take a crack at it. He approaches the horse and whispers something into his ear. Immediately the horse bursts into laughter. The man walks up, retrieves the jar of money and leaves. Two weeks later the same man enters the bar again to see another jar of money and the same horse in the corner. Curious again, he asks the bartender "Well, what's the deal with the horse and the money this time?" The bartender replies: "If you can make the horse cry, the money is yours." The man walks up to the horse whispers something into the horses ear and the horse follows the man into the bathroom. 30 seconds later the horse and man walk out of the restroom and the horse is in tears. The man walks up to the bar to grab the jar of money but before he does the bartender asks: "Hey I have to know, how did you get the horse to laugh the first time and cry this time?" The man says: "Well it was easy, the first time I told him my dick was bigger than his." "The second time I showed him."
