From my experience, Astralians have a great sense of humour and provided they know any micky-taking is not meant seriously or done with venom, they laugh along; which is how I feel it should be.
The trouble with the world today - in MY humble opinion (and who cares what *I* think lol) - is that on the whole, everything is too PC and we've lost the ability to laugh at ourselves. Too many people take everything far too seriously nowadays. Fun songs like this have been around for centuries, and long may they live. lol
