I'm pretty sure I've had nightmares where my alarm clock is flying just out of reach so I can't turn it off, beeping and beeping and beeping. If I had one of these Flying Alarm Clock, that dream would become a waking reality. The clock works like you'd expect an alarm to, but has an ominous little propeller up top that shoots off when it's time to get up. You won't be able to turn it off until you retrieve the prop and return it to its holder on the clock. Just don't sleep with your face toward the ceiling, or with any of the windows open.

The Flying Alarm Clock, by Get Organized, sells for around $30.
