Mr Rudd & HM The Queen

At his meeting with Queen Elizabeth Australian Prime Minister Kevin Rudd turned to the Queen and said:
As I'm the Prime Minister, I'm thinking of changing how my great country is referred to, and I'm thinking that it should be a Kingdom."
The Queen replied, "I'm sorry Mr. Rudd, but to be a Kingdom, you have to have a King in charge - and you're not a King."
Rudd thought a while and then said: "How about a Principality then?"
To which the Queen replied, "Again, to be a Principality you have to be a Prince - and you're not a Prince, Mr. Rudd."
Rudd thought long and hard and came up with "How about an Empire then?"
The Queen, getting a little annoyed by now, replied : "Sorry again, Mr. Rudd, but to be an Empire you must have an Emperor in charge - and you are not an Emperor."
Before Rudd could utter another word, The Queen said: "I think you're doing quite nicely as a Country."
