Because of the Sonic Grenade, the modern office place is no longer a sanctuary of peace and quiet with the only audible sound being the clickety-clacks of the keyboard and the humming of the fluorescent lights. Pull the pin, toss the grenade in your "enemies" cube, and wait 20 seconds. The Sonic Grenade will go off letting out a continuous sound that can only be stopped by reinserting the pin. Now, who has the pin? You do.
Made of hard rubber and plastic, and comes with three volume settings. Find it on ThinkGeek.
