It is now February 29th of a leap year and Jamal lies every February 28th.

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?
