Sorry, I'm a Star Wars nerd and that is always the first thing that comes to mind for me...:oops: Useless Star Wars info from Wookiepedia; "Hammerhead was a common name used in reference to Ithorians, which referred to the shape of their heads. Ithorians themselves found the term to be highly offensive. 'Meerian Hammerhead' referred to the Ithorians of Bandomeer."
