"This theory was (jokingly) suggested to Fermi himself by his fellow physicist, Leó Szilárd, who suggested that extraterrestrials "are already among us - but they call themselves Hungarians", a humorous reference to the peculiar Hungarian language, unrelated to most other languages spoken in Europe."
