There are six zeroes in a million,
Nine in a billion,
Twelve in a trillion,
And fifteen in a quadrillion.
But now it's time to decide,
That eighteen zeroes make a squillion.

Globalisation has meant that the British have conceded to the Yanks and so British billions and trillions are now the same as American ones. (We have to let our Yankee friends win the odd battle, it's diplomacy.)
But, who is to decide what 18 zeroes are going to be called?
I vote for the squillion.

There are six zeroes in a million,
Nine in an American billion,
But twelve in a real Billion,
So a Trillion needs about eighteen or maybe twenty four...
Bad old joke...
Advisors come to G W Bush and say "Sir, three Brazilian soldiers have been killed in Afghanistan". Bush gets down on his knees, and prays loudly for a while, then says "Say, how many is a Brazilian, anyway?"
