Just a few weeks ago I met a guy with the same first name, but his last name was Head. No joke. I spared him the jokes.

Bet he wishes his surname was Bastard. Rich Bastard.

That's great! He is a friend of a friend of my mother, I'll suggest that she call him that!

Dick is a normal, be it old-fashioned, first name in The Netherlands.

Sure, but Dick Head is far more commonly expressed as an expletive than as a name.
