Really funny jokes-Native language

Two anthropologists fly to a south sea islands to investigate a natives. They go to dual adjacent islands as well as set to work. A few months after a single of them takes a canoe over to a alternative island to see how his colleague is doing. When he gets there, he finds a alternative anthropologist standing between a organisation of natives.

"Greetings! How is it going?" says a on vacation anthropologist.

"Wonderful!" says a other, "I have detected an important fact about a local language! Watch!"

He points at a palm tree as well as says, "what is that?"
The natives, in unison, say "Umbalo-gong!"
He then points at a rock as well as says, "and that?"
The locals again utter "Umbalo-gong!"

"You see!", says a beaming anthropologist, "They use a SAME word for 'rock' as well as for 'palm tree'!"

"That is truly amazing!" says a dismayed on vacation anthropologist, "On a alternative island, a same word means 'index finger'!"
