The second most annoying alarm clock is the Sonic Alarm. It will wake pretty well anything up! Haha… So to set the alarm, simply pull the pin, yell an emphatic “fire in the hole” and lob the grenade into the sleeper’s room. Then, after ten seconds a very annoying and piercingly loud noise (there are three volume settings specially for different person needed) will blast out from the alarm. That’s not all however, what makes this especially great is that to stop the alarm the sleeper has to find you so you can put the pin back in. Haha… and the hole to put back the pin is really tiny.
Price of this clock is around $19. Buy it here
