Hingefreel

The Hingefreel are an alien species native to the planet Arkintoofle Minor. They are briefly mentioned in the first chapter of Douglas Adams' Mostly Harmless as having invented a manner of faster-than-light travel by constructing spaceships powered by bad news. Though they found that bad news do in fact travel much faster than light; the vehicles ended up being quite problematic as no matter what the destination was, they were always received unwelcome at the arrival.
