Blue Man Group
The Blue Man Group is an exclusive group of Portugese prostitutes whose primary goal is to knock up every known species of salamanders with impunity intact. So far, they have failed 57 times. Years ago, they gave up that dream and are now working with PETA on the ultimate mission of splattering paint on *fake* fur coats.
Their evil plot
The plan of the Blue Men is simple:
Turn everything in the world blue.
Yes, this seems stupid, but in their culture, turning a planet blue means that they have conquered it. Why do you think Neptune is blue? No, it's not because it's a gaseous planet or whatever. That's exactly what the government wants us to think, so there isn't an outbreak of mass panic. They got Magrathea too! And, why is the sky blue? Not because of refracted sunlight. THEY did that! Their latest project is the ocean. So far, they've only been able to blueinate the Carribean.
What we can do
Basically, when it comes down to the big picture, we can't do shit. However, there are some things that we, as individuals, can do to slow down their progress.
The wisest thing to do however, is to consult a UFO expert or someone who has had experiences with aliens, such as Eric Cartman (Who was anally probed, twice), Dib (who's neighbor is an alien), or Homer Simpson (Who has had multiple encounters with aliens, one in fact being his boss.) Also, you could try to get in contact with crazy people like Fox Mulder, who believes that pretty much anyone at any time could be an alien. Or do the smart thing and stop the blue men yourself.
