Call The Sandman
Jon was very tired after a long day of work. He went to bed at 10 p.m., wound his alarm clock and set it for noon the next day. Since Jon fell asleep almost immediately, how many hours of sleep did he get before the alarm woke him?
HintRead it carefully.
AnswerTwo hours. Wind-up clocks can't be set more than 12 hours in advance, so the clock assumed Jon meant midnight.
