May 21, 2011 is the end of the world, since Aperture Science is testing their BIGGEST Portal Gun the size of Germany!

Another end of the world conspiracy bullshit! *sigh*
Okay, okay, fine...
GLaDOS is just testing it's new Portal Gun.
Or you could buy a Portal Gun and a SpaceSuit since Portals can be used on Moondust surfaces.
Ha! If you believe in this shit they're just gonna RickRoll you, it's embarrassing.
