A man goes into a bar and see's a sign that says $200 if you can make the horse laugh! So the guy goes over to the bartender and says I can make the horse laugh. The bartender say go ahead, the guy walks over to the horse and whispers in his ear the horse starts laughing hysterically.
The guy goes over to the bartender to get his money and the bartender says I bet you this $200 plus $400 more that you can't make the horse cry, the guy says alright you're on. He walks back over to the horse well the bartender turns around for a second and when he turns back around the horse is crying.
So he says to the guy before I give you this money I gotta know, how did you make the horse laugh? The guy said I told him my dick was bigger than his. The bartender say well how did you make him cry? The guy says I proved it.
