Lewis Black had a bit where he claims real social workers approached him with horrible names kids were given, including Ah-show-lah, which is spelled A-S-S-H-O-L-E. Even worse, in a manner of speaking, was 'Ab-sih-day'...spelled A-B-C-D-E. If these are true, some parents just don't care from the get-go.
Also, LONG ago I read an article about Brazilians taking names to an art form...kind of. One example was a man who's middle name was basically his entire Birthday. By entire I mean, like, David Wednesday-the-twenty-eighth-of-October-nineteen-hundred-and-eighty-one Clark.
Also, I read somewhere that in Brazil you can't give animals human names because it may be degrading to humans with those names. I cannot confirm this.
