I had this book when I was in elementary school "explaining" the origins of various superstitions. Thus I was debunked at a young age and never really bought into superstitions, bent spoons, UFOs or any of that stuff.

But if I give a knife as a gift, I'll enclose a penny so the recipient can give it back to me -- because you should never GIVE a knife, but it's okay to SELL one.
