This reminds me of another weapons-based alarm clock- Gun O’Clock. These are both perfect for making sure your one night stands stay that way. Nothing says KTHX now GTFO like someone tossing you a beeping hand grenade at the crack of dawn. Oh, and check out the Engrish in the graphic- Booon!! It looks like they also have a soccer ball version of this clock that won’t stop beeping until you hurl it across the room, which makes the grenade version a great training device for the real thing.
