A Jewish joke.
So this guy is caught by an evil bad guy. "You owe me $1000" he screams, "and I'll kill you if you don't pay me!"

"Look, you know I don't have any money. But I'll tell you what. Keep me here for a year, and I'll teach your horse to speak!"

"Sounds good. But I'm warning you: in a year's time, if my horse can't speak, I'LL KILL YOU!"

Later, the guy's friends ask him: "Are you crazy? How are you going to teach a horse to speak, when you're afraid of animals?"

"Look, a lot can happen in a year. Maybe the bad guy will die. Maybe his horse will die. Maybe I'll die. And maybe, just maybe, the horse will start talking!"
