Herodotus tells a story of egyptian kings (iirc) trying to figure out which people is the oldest. They put a few kids in a barn and servants fed them through a hole or something. The kids eventually blurted out something and the king sent messengers everywhere to find out if they have that sound as a word. It ended up meaning "bread" in a language I can't pronounce nor remember how to spell.

The good old days when experiments were done without any common sense whatsoever...
