Thanks for looking good Ferrick. One website with the story is linked below. I actually first heard the undigested centrum story from my father a few years ago, then I heard it subtly referred to on the radio during what was clearly some liquid vitamin product's plug. It seems possibly legitimate. I just can't tell.
