And while unusual names may be a Hollywood staple, some believe it may cross the line in the real world.
One New Zealand judge even blocked one family from using the name it chose. The judge said the name was unfair to the child.
"Initially, the reaction is, 'Are you for real?'" said Pat Wheaton, the New Zealand father who was blocked from naming his son 4Real.
Wheaton said the idea for the name came when the couple saw the first scan of the child.

And French parents must choose from an approved list. The laws are designed to prevent teasing.

"You can't use a four letter word that I wouldn't use in this interview anyway, and other than that you're free to do what you want," said New York University Sociology Department Chairman Dalton Conley. "That's part of the first amendment right to free speech here in America."
Only as the children grow up will people learn if these interesting names will be the source of ridicule.
