god only knows

so Mrs VVB is flicking through the TV channels and suddenly there's Tony Abbott and I hear him say "...like you, sir, we are one nation indivisible under God..."

At that stage I started ranting and Mrs VVB was obliged to, again, (a) warn me of the dangers of going on like that and (b) change the channel.

Umm...we're not, are we?

Also, I suspect in this case 'sir' is capitalised.
