If this isn't a comedy bit, there are educators with brains, fortitude and a sense of humor still teaching in Australia:
This is supposedly the message that the Maroochydore High School, Queensland, Australia, staff voted unanimously to record on their school telephone answering machine. It is claimed to be the actual answering machine message for the school.
I am quite skeptical. I just called the school, and got a normal sort of message providing the school office hours and an opportunity to leave a message. If the YouTube message was real, it has been removed. If it isn't a real answering machine message, then it was good laugh.
