Another thing that irks me is parents who give their kid a normal name, but with an outrageous spelling, just to be different. In my experience, this phenomenon tends to manifest itself in the, um, trailer-dwelling crowd.
I've always associated that with the upper-middle class.
The trailer-types I used to know (all white folks) usually had names like "Lafonda" for the girls and something either normal or ridiculously masculine for the boys.
My mostly-white church has a largely-black Sunday School population. One of the boys was attending for a few years when they realized that his name was not "Leshawn," but "Lil' Shawn."
They should name one of them Cirith Ungol.
Why not go all the way and call one Shelob? Ooh.
