* Here's my favorite: An engineer and a mathematician are hired to work at a company full of pranksters with low safety standards. One day, while they're at lunch, their officemates set fire to their trash cans. The engineer comes back from lunch, sees the fire, grabs the fire extinguisher, and puts out the fire. The mathematician returns shortly after that, grabs the fire extinguisher, and puts out the fire. The next day, the pranksters set another fire, but hide the fire extinguisher in a closet. The engineer gets back from lunch, sees the fire, searches the building, finds the fire extinguisher, and puts out the fire. The pranksters naturally hide the fire extinguisher again before the mathematician returns. The mathematician gets back from lunch, sees the fire, searches the building, finds the fire extinguisher, puts it back where it belongs, says "This is a known state," and sits down to work next to the burning trash can.
