“If aliens from outer space ever come and we show them our civilization and they make fun of it, we should say we were just kidding, that this isn't really our civilization, but a gag we hoped they would like. Then we tell them to come back in twenty years to see our REAL civilization. After that, we start a crash program of coming up with an impressive new civilization. Either that, or just shoot down the aliens as they're waving good-bye.”
