Laura Wattenberg at the Baby Names Blog was apparently conflicted over this particular name:
Is a two-headed alien a good enough reason to keep such an unlikely name in our baby name encyclopedia? My first instinct was no, but my husband disagreed. A certain sort of person, he argued, will indeed want to learn about the name Zaphod. He works for Google, so I accept his expertise on that “certain sort of person.” It made me wonder … has anyone actually named a baby in honor of Mr. Beeblebrox?
Sure enough, the U.K. is home to at least three Zaphods and even more boys with that middle name, all born since the Hitchhiker’s series premiered.
In terms of “geek purity,” the name has a great deal to recommend it, she says:
[T]he original Zaphod wasn’t some sleek, all-powerful force of light or darkness. He had a self-confident charm, but was voted “Worst Dressed Sentient Being in the Known Universe” seven times.
Having seen entirely too many Magic: The Gathering sessions in my day, I have to figure that Beeblebrox had to work really hard for that accolade.
And now I wonder if any of those young Zaphods were dubbed Zaphod the Fourth.
