A man walks into a bar and orders a beer, and sees a large jar of $10 bills sitting on the bar.

"What's with the large jar of money?" he asks the bartender.

"We're having a little contest. You put $10 into the jar, and go out back and try to make the horse laugh. If he laughs, you get all the money. There's only one week left, and if no one gets it the jar is mine, almost $500!" the bartender replied

The man decided to give it a go. He put his $10 in the jar, and headed out the back door. A few minutes later he walks back in, the bartender looks back, and the horse is rolling on the ground laughing histerically.

"Thanks for the beer." the man said, "Now I'll take my reward and head on home!"

The bartender was baffled and disappointed that he didn't get the money, "Not so fast" he replied as he secured the jar. "Double or nothing, if you can make the horse cry it's yours." He took $500 out of the register and slammed it on the bar next to the jar.

"You know what, you're on!" the man said, and pulled $500 out of his walled and put it on the bar.

The man once again headed out the back door. A few minutes later, he walks back in, the bartender looks back, and the horse sobbing uncontrollably.

"Thanks for the money!" the man said.

As he was packing up his new fortune, the bartender pondered. No one had even made the horse twitch, let alone laugh AND cry.

"How did you do it? I have to know!" the bartender asked.

The man replied "The first time I walked out, I told the horse my cock was bigger than his. The second time, I showed him!"
