Blackboard has long ago seized enough treasure to cease sailing the seven seas. He's not sure that
   there were actually seven seas, but he figures he might have sailed some of them more than once, so
   for the sake of the ever so important alliteration, he claims there were seven. Due to his
   illiterate shipmate who once made a spelling error when they signed up at the Office of Piracy, he
   has had to suffer, all his life, from chalk jokes and people scratching him to try to make him
   screech. Both chalk jokers and scratchers have usually found themselves swiftly and painfully
   deprived of their ears or other suitable bodyparts.
