Top Ten Most Annoying Alarm Clocks

I'm especially intrigued by the Sonic Alarm. As you all know, the 'Cub is the world's heaviest sleeper, and usually I have to march into his room with two very large skillets and bang them together for two or three minutes before he'll deign to open an eye and ask what I'm doing in there and would I please stop. (For once, I'm not exaggerating.) By that point, my ears are usually ringing and it seems like a lot of trouble.

The Sonic Alarm is basically a grenade with a ten second "fuse" that I can toss onto his bed. It doesn't turn off until someone replaces the pin. That sounds like a much better deal for everyone. And by "everyone", I of course mean "me".
