Yes, this stuff is all sorta kinda fun, but pointless.
Perhaps it was an interview question? If so, it doesn't say much for the interviewer. There are a small set of tricks like this, which people can easily learn for interviews, without actually knowing much about programming at all. Whereas many good honest candidates wouldn't know the answer, because they've been too busy working on real projects!
Interviewers should ask searching questions with longer answers, where it's much harder to fake a good answer. Of course, if the interviewer's own technical knowledge is lacking, and they're only looking for the "right" answer they've got on their crib-sheet, there's trouble there, too.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.
