Here's a thought, shouldn't Worf technically have a last name? Yeah, I know, Klingons only have one name, and in formal situations mention their father's name to identify themselves (Worf, son of Mogh) but since Worf was adopted by the Rozhenkos, shouldn't he be Worf Rozhenko? Alexander is known as Alexander Rozhenko, even when he was serving in the Klingon military, so why doesn't Worf use the Rozhenko name. I know he's proud of his Klingon heritage, this seems somewhat disrespectful of his human parents.
