"Umbalo-Gong" joke
Santa and Banta fly to the south sea islands to study the natives. They go to two adjacent islands and set to work. A few months later Santa takes a boat over to the other island to see how Banta is doing. When he gets there, he finds Banta standing among a group of natives.
"Greetings! How is it going?" says Santa.
"Wonderful!" says Banta, "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 intone, "Umbalo-gong!"
"You see!", says the beaming Banta, "They use the SAME word for `rock` and for `palm tree`!"
"That is truly amazing!" says the astonished Santa, "On the other island, the same word means `index finger`!"
