If you have to get up in the morning -- and I don't recommend that for health reasons -- then you might as well do it in an exciting way. Michael Krumpus made a clock that looks like a bomb from the movies. Cut the right wire and you'll disarm it. Cut the wrong one, and either nothing will happen, or it will detonate immediately.
