A man wakes up bent over in pain in the middle of the night. The pain is so bad he goes to the hospital. A doctor sees him and explains that he was born with three testicles and the third one just descended. No big deal says the doc, it's a simple procedure and he can do in an hour.
The guy tells the doc he's a player and has been waiting for something like this all his life. He gets dressed and heads for the nearest bar. There's only one other guy in the bar besides the bar tender and the guy bets him $500 that between him and the bartender they have five testicles. The bartender hears this and starts trying to get the guy's attention but the guy is too hopped up.
The other guy in the bar says that the bet is so ridiculous he'll take him up on it, and takes $500 out of hjis wallet and sets it on the bar.
The bartender looks at the guy who offered the bet and says, "Buddy, I hope you were born with four."
Morale of the story: There's no such thing as a lock.
