I've always felt that unusual names add a bit of flavor to one's personality. Partially it's personal bias, since "Guy" is at least a moderately unusual name in the U.S. (although I'd fit right in in France or the U.K.). But there is such a thing as taking it too far.
And the parents in New Zealand who named their child "Talula Does The Hula From Hawaii" arguably have gone that far, and then some. A judge sensibly allowed the child to change her name to something more reasonable.
Also entertaining from the article were some of the other names that people have attached to their offspring -- my favorite is "Number 16 Bus Shelter."
