"What was the self-sacrifice?" "I jettisoned half of a much-loved and I think irreplaceable pair of shoes."… — Douglas Adams

"What was the self-sacrifice?"

"I jettisoned half of a much-loved and I think irreplaceable pair of shoes."

"Why was that self-sacrifice?"

"Because they were mine!" said Ford, crossly.

"I think we have different value systems."

"Well, mine's better."
