From BBC News:
This case actually took place in February, but the courts are only now releasing the information to the public.
A court in New Zealand took custody of a nine year old girl so she could change her name. She hated her given name. She told people to call her "K," and she refused to tell anyone her given name.
Her given name was "Talula Does The Hula From Hawaii."
The judge in the case said, "The court is profoundly concerned about the very poor judgment which this child's parents have shown in choosing this name." The court allowed her to change her name, but (of course) the article does not say what her name is now.
The article also says that New Zealand courts had previously blocked the use of the names "Sex Fruit, Keenan Got Lucy and Yeah Detroit, . . . but Number 16 Bus Shelter, Violence and Midnight Chardonnay had been allowed."
Furthermore, there are comments on the BBC story from "Russell Sprout," "Craig Gogay," "Jenna Dana Bananarama Rater" (Jenna Rater, for short -- she admits that she deliberately changed her name to be this), "Egnorwiddle Waldstrom," "Ftango Molasses" and "Mangled Brown Fence-Post." I suspect that a couple of these people are just 'avin' a larf....
