What's in a name?

Sommer learned this bit of trivia at school this week and I thought it was rather interesting. Never heard it before.

How the Kangaroo got its name...

When European explorers first saw these strange hopping animals they asked a native Australian (aborigine) what they were called.
He replied "kangaroo" meaning "I don't understand" your question.
The explorers thought this was the animal's name. And that's how the kangaroo got its name.
