Certificate of Authenticity:

While flying, we browse the Sky-Mall magazine. I’ve noticed that one can buy a gold ring, the “One ring to rule them all” with the appropriate Tolkien inscription. What fascinates me is that the thousands (or perhaps, dozens?) of people who buy this ring get a “certificate of authenticity.” I imagine the certificate says something like this:

Congratulations! You have purchased the one and only authentic ring to rule them all. Everyone else (including the manufacturer) has a fake.
