Fire!

When I started college in Boston a hundred years ago, we had this professor, you know the type. He would start each day off by writing the topics down on the board. One day, he wrote the topic FIRE. Instantaneously, the entire room yelled out FIRE! We were all big Jim Morrison fans and his prompt had sent us into a frenzy. He dropped his chalk and lost his composure. The Doors had a way of knocking you for a loop in those days!
