Well I am not sure you've really got the spirit of the thread Heaps Good! It's all tongue in cheek, bit of fun... and judging by what Sam kekovich can get away with in his Australia Day broadcasts, really we can all have a laugh together can't we?
Anyway. I have been married to an Australian for 10 years so I know what kind of laugh I can have with him, his family... and so far they are all still talking to me. And enjoy a laugh at these things too.
Plus I think even MIL has managed to get a grip with the boys calling certain footwear flip flops. :)
