LOL, well now that you mention it, yes. My mom had 3, and I was just 6, and did not think there would be any more, but 3 more came along. There were 4 years between numbers 3 and 4, so maybe it did work for 4 years, but not indefinitely. I never asked my mom if she wanted 6, but if not, my only point is, that it did not work.
