Super Computers

The Pentagon recently unveiled it's new super CRAY computer to the top brass. This fantastic device, capable of making bazillions of decisions in split nanoseconds, is designed to solve all military problems with the greatest of ease. To test it's capabilities, the brass pose a tactical problem to it and then ask for a decision, "Attack or Retreat"?

CRAY hums a bit, blinks a myriad of lights and answers "YES".

The brass, somewhat confused by this answer, replied "Yes What"?

CRAY instantly replies, "YES SIR"!
