Just recalling a funny incident from my past
A few years ago when I was living in Pensacola, Fla I had occassion to go the the Baptist Hospital in Pensacola.
My friend and I entered the hospital and boarded an elevator to go to the third floor. While waiting for everyone to board the elevator I happened to look up and someone had removed a service panel in the elevator car ceiling exposing a small exhaust fan similar to the type we have in the bathroom.
You could see the little fan blade spinning and I commented.."I don't think that liitle propeller is gonna be big enough to lift this whole load".
With that,,there was a huge woman standing by the door, she glanced up and screamed,,,"Let me out" so someone hit the button to open the door and she made a mad dash out of the elevator.
