Washington, D.C.—The American condiment community reacted with shock Monday when the U.S. Department of Natural Resources announced that the nation’s natural mayonnaise reserves, long thought sufficient to carry the country into the 21st century, are, in fact, running dangerously low.

“Because of record heat in the Southwest basin, the outer layer of our national reserves spoiled prematurely,” DNR spokesperson David Korking said. “Millions of gallons of all-natural mayonnaise—mayonnaise that hundreds of species of waterfowl rely on to make wholesome egg salad—have, in effect, become a lethal poison.”

The DNR warned that the mile-deep wells that line the Pacific coast as well as the Gulf of Mexico, now must be tested extensively before being tapped and imported to U.S. processing plants. The DNR did unveil a plan to scoop and dump all spoiled mayonnaise into deep space, while at the same time stepping up measures to drill the forests of Alaska for fresh wells.

As of market-closing Tuesday, mayonnaise prices were up over four dollars per drum.
