Hey, maybe I can derail the holy war with a joke.
A firefighter, an engineer, and a mathematician are in adjoining hotel rooms. Through an amazing coincidence, a small fire breaks out in the wastebasket of each room.
The firefighter sees the fire, rushes into the hall, gets the fire hose, and puts out the fire.
The engineer sees the fire, notices a water glass in the room, does a quick calculation, fills a glass with water from the sink and puts out the fire.
The mathematician sees the fire, notices a water glass in the room, says "trivial!" and goes back to bed.
