]If you are scuba diving, be sure not to swim anywhere near any
]ship or installation that has been protected by the Raytheon
]Corporation's new "swimmer denial" system. Otherwise you will very
]quickly feel extremely sick and probably drown.
]
]Raytheon?s underwater sensors detect any unwelcome presence and
]trigger an underwater sound system that emits extremely powerful
]pulses of low frequency audio. The pulse rate and audio frequency
]are chosen to make human organs resonate like organ pipes, causing
]swimmers to vomit into their masks or suffer internal ruptures.

Remind you of anything you've heard before?
