I believe that in Scandinavian countries, at the ripe age of 8, a child is dubbed a part in a metal band, and then that night, the rest of the band sprouts from the 8 year olds body.

To keep it secret, the neighbors friends adopt the other children, and at the age of 12 a manager magically appears at the door and gives them a record deal.

That is my unreasonable reason for why there are so many talented musicians in the Scandinavian countries!

Do you have any unreasonable reasons for things? =D?
