The Aliens

The Aliens came to earth last night and spoke with me and they told me their plan.
They said, "We need the water".
I said, "What?"
They said, "The water, we need it, the water on the earth... It's ours, ya' know, and we need it back."
I said, "Yours?"
"Oh yeah," the alien said, "it's ours from eons ago. A long, long time ago the science department wanted to see what would happen if we put out the fire on the surface of a trashball, and just let it burn down inside til it was coal. Somebody thought it would collapse and disappear... make it easier to navigate space... so we dragged a huge ice cube here and slammed it into this trashball after successfully setting it on fire. It worked; the surface of the trashball was extinguished and the core was burning as planned but the planet was developing some form of bacteria that had evolved to the point that it was sending objects into space and the Supreme Board couldn't have that, so they ordered the return of the water to our world, and to start the experiment again closer to home where we can keep a closer eye on things... and spray."
"But what about Earth?"
"The trashball? Normal procedure; it will be dragged slowly into the big incinerator at the center, a few balls in front of it. Initially, they were going to slap the place with a comet, like the first time they tried to stop a fungus, but the scientists said without the water the growth would stop... so they're not going to send a rock."
"But there's life here," I said.
"Tell that to the guys that want the water," the alien said. "I hear OILPS ain't got water for their pools... you know how OILPS are! Without water for their pools they got nothing fo sit beside and drink. They got no place to tan, ya know... they need that water. Without it the OILPSROCK wouldn't be the haven it is."
"But do they need it to survive?" I asked.
"Oh, hell no," the alien said. "They just like the way it looks, but they have eminent domain over this trashball. When the place goes up in steam don't worry, we're just heating the it up so we can suck off the moisture."
