I found this joke, and loved it! And of course, I had to share it!

An engineer, a physicist and a mathematician are staying in a hotel while attending a technical seminar. The engineer wakes up and smells smoke. He goes out into the hallway and sees a fire, so he fills a trashcan from his room with water and douses the fire. He goes back to bed.
Later, the physicist wakes up and smells smoke. He opens his doorand sees a fire in the hallway. He walks down the hall to a fire hose andafter calculating the flame velocity, distance, water pressure, trajectory,etc. extinguishes the fire with the minimum amount of water and energyneeded.
Later, the mathematician wakes up and smells smoke. He goes to the hall, sees the fire and then the fire hose. He thinks for a moment and then exclaims, "Ah, a solution exists!" and then goes back to bed.

I hope I am not the only one who enjoyed that! :)
