The Tale of the Scientist and the Car

[quarrel]

"Who here understands science? Raise your hand."

(pause)

"Hmm. That's not many. Okay, let's start over. Different question. Who here has ever driven a car? Raise your hand.

"Ah. I see that's more. Good. Okay, those of you with your hands up, keep them up up if you ever got in your car, turned the key, and nothing happened. Dead. Wouldn't start.

"Now keep them up if you thought to yourself, 'The battery's probably dead.'

"And keep them up if you then tried flicking on the radio or the headlights or something to test if the battery really was dead or if it was something else.

"All of you with your hands still up: guess what. You understand science."
