A rich millionaire decides to throw a massive party for his 50th birthday, so during this party he grabs the microphone and he announces to his guests that down in the garden of his mansion he has a swimming pool with two great white sharks in it. 'I will give anything they desire of mine, to the man who swims across that pool.'
So the party continues with no events in the pool, until suddenly, there is a great splash and all the guests of the party run to the pool to see what has happened.
In the pool is a man and he is swimming as hard as he can, and the fins come out of the water and the jaws are snapping and this guy just keeps on going and the sharks are gaining on him and this guy reaches the end and he gets out of the pool, tired and soaked.
The millionaire grabs the microphone and says, 'I am a man of my word, anything of mine I will give, my Ferraris, my house, absolutely anything, for you are the bravest man I have ever seen. So sir what will it be?' the millionaire asks.
The guy grabs the microphone and says, 'Why don't we start with the name of the bastard that pushed me in!'
