And now, I'm thinking Hitchhikers...
"The trouble began when the computer Hactar launched a fake spaceship to crash-land on Krikkit, suddenly alerting the inhabitants thereof to the possibility of life beyond their sphere. Within a year they had stripped every tiniest last secret out of its wreckage and constructed their own spaceship, Krikkit One, which they used to view the outside Universe for the first time. Unable to reconcile its existence with their traditional worldview, they transformed overnight from charming, delightful, intelligent, if
whimsical, ordinary people, into charming, delightful, intelligent,
whimsical, manic xenophobes. And so, charmingly, delightfully, intelligently,
whimsically, they decided to destroy it."
