[William Porter is wheel-tapping a train]
Managing director's wife:
You may think me a little stupid, but why do they tap them?
William Porter:
Well, you see, madam, it's like this. If I tap the wheel with this hammer and the wheel goes clang, then I know that the wheel's there.
Managing director:
But supposing that the wheel doesn't go clang?
William Porter:
Well, then I know that the train's gone!
