A woman came to the hospital to visit a friend

A woman came to the hospital to visit a friend.

She had not been in a hospital for several years and felt very ignorant about all the new technology.

A technician followed her onto the elevator, wheeling a large, intimidating looking machine with tubes and wires and dials.

“Boy, would I hate to be hooked up to that thing,” she said.

“So would I,” replied the technician.

“It’s a floor cleaning machine.”
