Steel-toed boots. They effectively proved the myth wrong that steel-toed boots would cut off your toes if a heavy object landed on them. What it showed is that without them, your toes could be smashed beyond all recognition and that the boots do work. I've spoken to many guys who say they'd rather have their toes smashed than cut off. Really? Once they're smashed that bad, they have to be cut off anyway. Break open your wallets and buy the danged things. I knew they worked and I point out to many that this show proved me right.
Ok, I have to admit that I really don't watch the show all that often but that one stands out in my mind the most when thinking on it.
