A millionaire throws a massive party for his fiftieth birthday. During the party, he's a bit bored and decides to stir things up a bit. He grabs the mic and announces to his guests that down in the garden of his mansion he has a swimming pool with two great white sharks in it. He offers anything he owns to anyone who will swim across that pool.
The party continues for some time with no one accepting his offer, until suddenly there's a loud splash. All the party guests run to the pool to see what has happened, and in the pool a man is frantically swimming as hard as he can. Fins come out of the water and jaws are snapping and the guy just keeps on going. The sharks are gaining, but the guy manages to reach the end and he leaps out of the pool, soaked.
The millionaire grabs the mic and says, "I am a man of his word, anything of mine I will give—-for you are the bravest man I have ever seen. So, what will it be?" the millionaire asks.
The guy grabs the mic and says, "Why don't we start with the name of the person who pushed me in!"
