Bob the Meteorologist?

You know how films and TV shows often don't get it right when it comes to thunderstorms?

Bob the Builder is caught in a storm. There is a flash of light, together with a sound effect of thunder. Bob starts counting: "1… elephant… 2… elephant…". As he gets up to eight there's another simultaneous thunder noise and flash of light.

He explains to the others that he's counting the seconds between the lightning flash and the thunder. "It was eight seconds, so that means the storm is only eight miles away." Hmmmmm.
