Sonic Alarm Grenade

This may not be the newest product but is definitely a cool one. The Sonic Alarm is a alarm grenade (nice!). Simply pull the pin (with your teeth of course) and chuck it in your victims room. The grenade will then explode with a piercing noise. This is sure to wake up the person immediately. But how do you turn it off? Well the person has to find you, wherever you are by then, and take the pin to put it back in. This is sure to be nothing but fun. It sells for $16 at iwantoneofthose.com.
