Sonic Bomb Alarm Clock with Bed Shaker
This is probably the most hardcore alarm clock I have ever seen. You can turn the sound up to louder than a jackhammer (your neighbors will hate you) AND you can put the bed shaker under your mattress. Not only will a deafening beeping wake up you up but also an adrenaline rush because you may think there's an earthquake going on. Perfect for anyone who really has problems waking up. Oh, and there's a snooze button in case you can still go to sleep after all that mumbo jumbo.
