Mathematician Job Interview

A mathematician is interviewing for a prestigious job. To make sure he has the right morals, the interviewer gives him the following situation: "You're late for a meeting, when you come across a burning house, a fire hydrant, and a fire hose lying across the street. What do you do?" The mathematician responds: "People's lives are more important than the meeting. I screw the fire hose into the hydrant and put out the fire before coming to the office." The interviewer is impressed, but asks him a followup question just to make sure: "You're late for a meeting when you pass a fire hose connected to a hydrant, next to a perfectly safe house. What do you do?" The mathematician thinks for a moment, then replies: "I unscrew the fire hose, carry it across the street, and set the house on fire. Then I've reduced it to a problem I've already solved." via
