What if this plans starts an intergalactic war? Ever thought about that?
Picture this:
Opening scene from INDEPENDENCE DAY: the mother ship appears on the radar screens for the first time, instead of splitting into individual saucers, they send one out only, (it's their heavy duty model with mega-towing capacity), as it nears our atmosphere it suddenly stops, a huge hatch is seen opening and a giant alien foot kicks out a black plastic bag with something inside kicking and hollering "where's my meatloaf, headcheese and lambshank sandwich!", with a swift kick the alien foot directs the bag home to Earth.
Cut to the Mothership: Head alien to second in command: "those earthlings, poor devils, we just can't bring ourselves to invade them, they've got to live with that loud mouthed creature, it's just to inhumane, even by our standards, besides we dare not get them angry, they've discovered how to clone, they can clone an army of Rosies and cut then loose in the universe! The ultimate doomsday weapon! The thought.........too horrible.....must leave now! Quick warp 15!!! Now!!
