A long time ago, when England found that their jails could not hold the increased number of criminals, they found the easiest way out, by shipping all these guys to Australia. So basically the Australians are the descandents of the jailbirds that England didnt want to have in its own land. So it is not a wonder that Aussies behave the way they do.
Let us pray to GOD to cure them of their illness and teach them how to behave on a cricket field at least.
