Of nyce conscience took he no keep.
If that he faught and hadde the hyer hond,
By water he sente hem hoom to every lond.

– Geoffrey Chaucer

The Canterbury Tales, General Prologue. A rough man of the sea, the Shipman is not one to pick a fight with on board a ship. He has no conscience and if he beats someone in the fight he chucks them overboard. Don’t get into a competition with this guy!
