All I can come up with is a pun on Dorian Gray. But since the former was neither my first pet's name nor was the latter any street I lived on (as far as I can remember), maybe all that's going for it is the association with Earl Grey. Earl D. Gray. Instead of a hula-hoop-sized hat brim, Mizz Horse, you could walk around with a picture frame setting off your face. Now, that wouldn't be annoying, would it?
