A magician on a cruise ship is constantly having his tricks spoilt by the ships parrot, every time he does a trick the parrot shouts "It's in his pocket", "4 of clubs", "It's got a false bottom!" etc etc.
The magician hates it. That night the ship sinks and him and the parrott cling to a piece of drift wood.
For four days the parrott says f*** all, just stares at him.
On the fifth day the parrott says "Ok, I give up, where's the ship?!"
