When I was just a sprout we had a story we read in an English class. The story took place in Australia and had a kookaburra in it. The glossary at the end of the story defined the kookaburra as a laughing jackass. This is/was a slang phrase for the bird which has a call that sounds like the braying of an ass. In a quiz we were asked to define the word kookaburra. I was the only person who was interested enough to have noticed that the creature was, in fact, a bird. This includes the teacher. I was told that my answer was wrong.
