So a man walks into a bar...

And he sits down to have a drink, as he's drinking he spots a jar with money in it and asks the bartender what it's for. The bartender responds "oh its a challenge, if you can make the horse in the back laugh you can keep the money it's only five bucks to try." the man thinks about it and pays the five bucks. He comes back five seconds later with the horse laughing like crazy he picks up the jar and leaves. This went on for two more days and finally the bartender changes the challenge to making the horse cry. The man comes in and sees the change thinks about it and goes out, five seconds later he comes in and the horse is crying! Amazed the bartender asks "how did you do it" to which the man replies "on the first two days i told him my dick was bigger than his and today i showed him" :)
