Found this funny article from reuters . Apparently a chinese couple recently had a baby and wanted to choose the name "@"
Aparantly, the symbol has a special meeting in Chineese "love him"..so the story goes. The articles do not say if they were legally allowed to use this name.
I think it would be a cool name to have, and although the baby may be teased later in life, I can't think off my head a nasty school rhyme that uses "@". My understanding is that it's not pronounced "AT" like the common email pronounciation.
...I suppose they could have tried to name the baby Coca-Cola
