If you can make my horse laugh

[AlabamaNomadRider]

A man walks into a bar and sits down and orders a beer. He sees a horse in the back part of the bar. He also notices a sign that reads if you can make my horse laugh I will give you $100. The guy sitting at the bar asked the bartender if the sign is correct. The bartender told the man it was correct. The man gets up from his stool and goes back to the horse and whispers in its ear. When he comes back to finish his beer the horse is almost rolling with laughter. The bartender pays him and he gets up and leaves the bar. The horse was still laughing a week later when the guy walks back in the bar. The bartender says I don't know what you said to my horse but he has been laughing all week. If you can get him to stop him from laughing I will give you another $100. The guy says ok but I need to take your horse out back. The bartender says ok. The man walks out back with the horse and in a minute or so they walk back in and the horse is crying. He finishes his beer and collects his $100 and then leaves the bar. The horse cried all week. When the guy comes back the next week and orders a beer the bartender said you made my horse laugh and he laughed for a week. Then you made him cry and he has cried for a week. Would you please tell me how you got him to laugh. The man says sure, I went over and whispered in his ear and told him I was bigger than he is. Well how did you start him to crying. When we went out back, I Showed Him!
