A man walks into a bar and sits down at the counter...
He asks the Bartender for a beer and notices a pot of money sitting on the counter, he asks the Bartender "what is that pot of money for?" The Bartender replies "well that there is for anyone who can make my horse laugh or cry!" The man thinks to himself for a min and then asks "where might this horse of yours be...can I give it a try?" The Bartender replies "Sure you can son...He is out back, but I have to warn you no one has ever suceeded!" The man takes this challenge and goes out back with the horse, meanwhile the Bartender is laughing and listening...all of a sudden he hears his horse laugh, then he hears him start to cry. The mann walks in all proud and says "can I have my money now?" The Bartender says "Now hold on son I want to know how in the hell you did that!" The man replied "It was quite simple really...I made him laugh by telling him my d*ck was bigger than his!" The Bartender asks "And how did you make him cry?" The man says "I proved it!!!"

That's actually a true story, I got the money.
