(An SF short-short by Jeff Duntemann)

"Mr. Stypek, in the last six months that computer program of yours cut Federal government purchase orders for 18,000 'uninhabitable manufactured housing units' to a total of 21 million dollars." Senator Ralph W. Ruesome (R., Oklahoma) sent the traitor Xerox copies scattering over the Formica tabletop.

National Weather Service Programmer Grade 12 Bartholomew Stypek winced. "Umm...you gave us the money, Senator."

"But not for rotted-out house trailers!"

Stypek sucked in his breath. "You gave us 25 million dollars to create an expert system capable of cutting annual US tornado fatalities in half. We spent a year teaching STORMY everything we knew about tornadoes. Every statistic, every paper ever published on the subject we fed him, and we gave him the power to set up his own PERT charts and plan his own project. Umm...I preauthorized him to cut purchase orders for items under $2000."

"Which he did. 18,000 times. For abandoned house trailers. Which he then delivered to an abandoned military base in west Nebraska a zillion miles from nowhere. And why, pray tell?"

Stypek keyed in the question on the terminal he had brought from his office. STORMY's answer was immediate:

TO KEEP TORNADOES FROM KILLING PEOPLE.

Stypek turned the portable terminal around so that the Senator could see it. A long pause ensued.

Ruesome puffed out his red cheeks. "Mr. Stypek, be at my office at 8:00 sharp tomorrow. We're going to Nebraska."

The two men climbed out of the Jeep onto scrubby grass. It was muggy for July, and it smelled like rain. Stypek gripped his palmheld cellular remote terminal in one hand, and that hand was shaking.

Before them on the plain lay an enormous squat pyramid nine layers high, built entirely of discolored white and pastel boxes made out of corrugated aluminum and stick pine, some with wheels, most without. The four-paned windows looked disturbingly like crossed-out cartoon eyes. Stypek counted trailers around the rim of the pyramid, and a quick mental estimate indicated that they were all in there, all 18,000.

A cold wind was blowing in from the southeast.

"Well, here's the trailers. Ask your software expert what made him think stacking old trailers in the butt end of nowhere would save lives."

Lightning flashed in the north. The sky was darkening; a storm was definitely coming in. Stypek propped the radio terminal on the Jeep's fender and dutifully keyed in the question. The link to STORMY in Washington was marginal, but it held:

TORNADOES ALWAYS SEEM TO STRIKE PLACES WHERE THERE ARE LOTS OF MOBILE HOMES.

Stypek read the answer for the Senator. Ruesome groaned and kicked the Jeep hard with his pointed alligator boot. "Goldurn it, son, you call this 'artificial intelligence?' That silly damfool program bought up all the cheap trailers it could find and stacked them in Nebraska to get them away from tornadoes in the Midwest. Makes sense, right? To a program, right? Save people who don't live in empty trailers, right?"

The force of the wind abruptly doubled. Lightning flashed all around them, and huge thunderheads were rolling in from all points of the compass. Stypek could hear the wind howling through cavities between the trailers.

"I'm sorry, Senator!" Stypek shouted over the wind.

But Ruesome wasn't listening. He was looking to the west, where a steel-grey tentacle had descended from the sky, twisting and twitching until it touched the ground. Stypek looked south--and saw two more funnel clouds appear like twins to stab at the earth.

The programmer spun around. On every side, tornadoes were appearing amidst the roiling clouds, first five, then a dozen, and suddenly too many to count, all heading in defiance of the wind right toward them. The noise was deafening--and Stypek could now feel that deadly, unmistakable rumble of the killer twisters.

Stypek had felt all along that he had never quite asked STORMY the right question. Now, suddenly, the question was plain, and he hammered it into the terminal with shaking fingers:

STORMY: FOR WHAT PURPOSE DID YOU BUY ALL THESE TRAILERS?

The answer came back as a single word:

BAIT.

The winds were blowing him to the ground. Stypek dropped the terminal and grabbed the Senator by the arm, pulling him toward a nearby culvert where the road crossed a dry creekbed. He shoved the obese man into one three-foot drainpipe, then threw himself into the other.

A moment later, the tornadoes converged on the trailers, all at once. The sound was terrifying. Stypek fainted.

Both men lived. Local legend holds that it rained corrugated aluminum in Nebraska for several weeks.

And it was years before another tornado was seen anywhere in the USA.
