"theleveller says that people from Hull are called Codheads. That is the name for people from Grimsby."

Well, Les, I've always called them Codheads and I've got the scars to prove it (mostly acquired in Humber Street pubs in the late 1960s)...

Actually, I recently discovered that one side of my family hails from Hull - greatx5 grandfather was a whaler who was lost in Baffin Bay in the 1830s and great x3 grandfather was a sea captain. Really very embarrassing!
