A Flying Alarm Clock...

Interesting concept...I gotta get me one of those! Available at Boystuff UK
for 20 pounds.

You'll have to get up when this little baby starts, because it takes off and flies round the room, making a really annoying noise like a mosquito,

so you'll have to find it first, before you can turn it off. Even if you hit the snooze button, it will take off again, so it will undoubtedly get you out of bed, though of course it might smash the place up a bit before you catch it, and if you sleep with the windows open you might find yourself running round the garden in your jimjams (no way to wake up) and may frighten the neighbourhood dogs.

There's also a slight danger that if you are a really heavy sleeper, and the things flies around the room without waking you up, eventually it will run out of juice, so it could wake you up by dropping on an exposed body part, such as the head, though I suppose you'd at least be awake. Or unconscious, possibly!

However it's a terrific fun item, and has already won a technology design award for its innovation and flair and makes a neat gift for anyone who has trouble getting out of the old pit in the mornings.
