BETA QUADRANT, ZGYXANearly 200,000 hostile aliens from the planet Zgyxa skipped invading Earth Monday, saying it 'does not seem worth the effort.' 'A planet scan indicates that its resources will be tapped by 2015, its most intelligent life form cannot fly, and it possesses no significant deposits of Tangium,' said Supreme Commander Kasha Ak-Bej, the nine-foot serpentine leader of the invasion. 'Not to mention that their fleshy exoskeleton would make earthlings unfit slaves for mining Zgyxa's molten core.' Representatives from the Council of Earth expressed their disappointment.
