From the Midterm

Today's low traffic numbers mean either that everyone is taking advantage of the nice post-Frances weather or else they've noticed that I haven't done any real math lately (so I haven't posted about real math).

In any case. I gave a midterm today. The question:
There are two boxes: one marked A and one marked B. Each box contains either $1 million or a deadly snake that will kill you instantly. You must open one box. On box A there is a sign that reads: "At least one of these boxes contains $1 million." On box B there is a sign that reads: "A deadly snake that will kill you instantly is in box A." You are told that either both signs are true or both are false. Which box do you open?
Most amusing answer:
None of them there could be a snake in both A and B. The sign on Box A could fool a lot of people
