What foriegn accent would you choose to speak your native language in?

If you had to speak your native language in an accent from a country that doesn't speak that language, what would you choose.

 

For example, I'm Australian, so my native language is English. I can't choose an accent from the UK, US, Canada etc. because they already speak English. 

 

Another example: If you're from the Moon and your native language is Moonspeak, what foreign accent would you choose to speak Moonspeak in?

etc.

 

I'm still trying to think of what I'd choose - I'm curious as to what other people think.
