I had an employee once who was completely, utterly, totally consumed with his one goal in life: to create a fireproof pipe organ.
Apparently, and at least in his alleged mind, those tubes are a fire hazard, so I guess there's a reason for all those stories we hear about old European cathedrals just spontaneously bursting into flames.
It's the pipe organ!
I worked with a guy who was building a rocket ship to go to Mars.
I always suspected he was a closet serial killer. He was also allergic to bathing.
