Somehow, a set of instructions from aliens for how to make something arrives on Earth. No direct contact is made; the instructions (and maybe some other things) are the only things we get from them, and usually the only evidence the aliens exist at all. Naturally, scientists get to work following the instructions. Nine times out of ten, following the instructions leads to Very Bad Things. Usually the aliens planned this all along; perhaps they're softening us up for conquest. Examples:
Hello, Unknown Troper. You'll need to get known to lend a hand here.
