Two anthropologists fly to a remote island to find out more about the culture. They split up and go to either side of the island and get to work.
A few months later one of them takes a canoe over to the other side of the island to see how his colleague is doing. When he gets there, he finds the other anthropologist standing among a group of natives.
“Greetings! How is it going?” asks the visiting anthropologist.
“Wonderful!” says the other. “I have discovered an important fact about the local language! Watch!”
He points at a palm tree and says: “What is that?”
The natives, in unison, say: “Umbalo-gong!”
He then points at a rock and says: “And that?”
The natives again reply: “Umbalo-gong!”
“You see! They use the same word for rock and for palm tree!” the beaming anthropologist says.
“That is truly amazing,” says the visiting anthropologist, “On the other side of the island, the same word means index finger!”
