Heres something to try...

There are two subjects. Each was asked to pick a marble out of a bag. There are two marbles one Red and one Blue. However one of the subjects can only lie and is incapable of telling the truth and vice versa for the other. Determine which subject has the blue marble, you can only ask a total of two questions. To whom and what questions would you ask?

It might seem as if some of the information is missing but I guarantee you its all there. Basically the answer isn't so much locating the Blue marble as it is identifying which subject is lying.
