Now here's one another one for you guys:

>Fred shows you two boxes- one that is red and one that is blue - and you
may choose to take either. You know one of the boxes contains an explosive
boobytrap and the other contains a million dollars cash but you don't know
which box is which. You also know that Fred always lies or always tells the
truth on alternate days. You are allowed to ask Fred only one question. How
do you get the million dollars?  Stuart LaForge 



"Fred, if I had asked you yesterday 'which box has the bucks?' which would
you have told me?"

The box he indicates will be the bomb, so you take the other one.
