Evil King Raymond and the White Knight
TOM: The inscription on the gold box cannot be true, because if it is, then the inscription on the silver box must also be true.
RAY: And that can't happen.
TOM: So, the statement on the third box, the lead box, is the only one that can be true. I love it!
RAY: The statement on the third box is the only one that can be true. The first one must be false, and the second box, which says, "Rowena's picture is not in this box," is also false, which means that her picture is in that box!
TOM: The silver box. I love it.
RAY: Who's our winner?
TOM: The winner is Greg Frye from Scottsdale, Arizona. For having his answer selected at random from among all the correct answers, Greg gets a $25 gift certificate to the Car Talk Shameless Commerce Division.
