This isn't really a baby name, it's a last name. You won't believe this...
At one of my previous jobs, there were three people there whose last name was...Chicken. That's right,
Chicken. Think of those poor people:
"How are the kids, Mrs. Chicken?"
You'd half expect them to reply "Not so good. One of them just came down with the People Pox."
As for a bad baby name, I'd say...Elmo. I've never heard it used to name a real kid (thank goodness)...but I did know of a kid named "Jerzee" once. There's another one I heard of whose name was "Toto". I kid you not. That was his real name. Toto.
