Computer Wonders

A young man at a college was learning about the wonders of the newest computer programs. This newest program could answer any question you asked of it, as long as you provided your name and birth date.
The young man asked this question, “Where is my father?”
The computer printed out the answer “Your father is fishing in Minnesota.”
The young man said it’s incorrect because his father died 20 years ago. The professor suggested rephrasing the question so the young man asked “Where is my mother’s husband?”
The computer printed out “Your mother’s husband died 20 years ago, but your father is still fishing in Minnesota.”
