I was just flipping through a 16 year-old copy of Rolling Stone magazine (don't ask) and I come to a pop-up Camel cigarette ad. And it starts playing "Happy Birthday." Is that possible? I don't want to tear it apart, but there's got to be some sort of battery in there, right? And it still works after 16 years? Dang. That's pretty weird.
