DangerBomb Alarm Clock -- It will explode if you don't get up!

The Banpresto DangerBomb alarm clock, already available in Japan, is another device that forces you to complete a specific task to wake up. To turn off the alarm, you have to unplug three cables and then reconnect them in a certain order. If you don't reconnect them in time, prepare to face the "explosion" (fake, of course)! Truly ingenious.

It’s only 2366 yen (about 165 RMB) in Japan, but the catch is whether you can get it through customs to bring it back...
