A room mate of mine who slept so soundly that an alarm clock failed to wake him. A boarder next room was irritated, he slammed disgustedly the shanty wall.
In the next evening, I intentionally pulled out the clock battery.
The once irritated board mate had a sound slept too as expected and in fact he didn't catch up his cruiser ship final job interview that he took a month in preparation.
