There´s a weird legend in Brazil called: Cramulhão da garrafa (Bottle Devil).
If you want to be rich, sell your soul to the devil. Simple as that.
Make a pact with the man, than get a rooster egg(yes, an egg that got out from a rooster). Obviously it will be a special egg, fertilized by the devil himself. Incubate it till a little devil (about 6 inches) rise, than put him in a bottle and he will make you rich along your life.
In the end of your life, he will take your soul to hell with him.
