If you find yourself hitting the snooze button and falling asleep again, maybe you need the Flying Alarm Clock.

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.
