'My great-grandfather was the magician on the Titanic. I hear he went down very well.'
Think of a three-digit number...
'He couldn't afford a dove, but he won a parrot in a bet...'
Reverse it.
'the parrot used to give away the secret to all of his tricks, until...'
Take the smaller number away from the larger.
'the night that the Titanic struck the iceberg...'
You'll end up with a two or three digit number.
'they were both floating around on a life raft...'
Add each digit together.
'and after three days'
If you're left with a two digit number add those two digits together as well.
the parrot looked at him and said, 'OK I give up, what have you done with the ship?'
Your lucky number is nine.
