Proving that there is no limit to stupidity and rapaciousness, some loony Russian woman is sueing NASA for $300 million for screwing up her astrological future by knocking a little tiny divot off a comet she probably wouldn't even have known was there if not for the news publicity over Deep Impact. Her equally-loony lawyer claims that "The impact changed the magnetic properties of the comet, and this could have affected mobile telephony here on Earth."
Let's see you prove that claim in court, asshat. We'll wait while you travel in person out to the comet to measure its changed magnetic field. Better take REALLY sensitive instruments with you; neither water-ice nor methane are ferromagnetic materials. Oh, by the way -- how long can you hold your breath?
