Cell Phone Jammers
Sick of cell phone blabbermouths? Then jam them!
We've all wanted to strangle them before. There's nothing worse than some jerk blabbing away on their cell phone while you're trying to enjoy a movie, meal at a restaurant, or a nice quiet nap on the bus/train ride to work. You can try to send the offending mobile blabbermouth a few evil looks or the old "courtesy cough" but those passive aggressive gestures rarely work.
If you really want to shut down a dopey chatter box, then you'll need to acquire a cell phone jammer.
