The Sound Grenade

Sound Grenade generates a really, really annoying, nauseating and headache producing high pitched sound.

I installed it today and tried it out on my coworkers. Absolutely stunning in how it works. Instantly people start looking around to see what in the heck is causing that annoying sound.

Best part? I can't hear a damned thing. Not unless I point the speakers at my head. Apparently it's that frequency that you lose as you get older but kids can seem to still hear. Oddly, practically everyone else can hear it really well regardless of their age.

All those years working on jet engines paid off!
