Yeah, naming the background characters after the interviewed kids would create that kind of mess — all the recycled characters and common kid names, like Emma and Sandy. On the other hand, if we go by the production notes, they would end up with names like "BGC#43" or "Girl #7". As far as animation studios are concerned, BGC are nameless mannequins, who are as void of any personality or identity as furniture, as their only role is to fill-out the background.

But don't feel bad, as they are at least cataloged — most Wikis don't even bother with BGCs, do to the inability to give them any kind of name.
