Twenty Oh Nine by surprise.

Last night it was. Sunday.

Trying to get smaller son's attention just after eight in the evening - he only had so much time left before bed.

He wasn't paying that much attention. So I, looking at the digital clock:

"Come on, it's Twenty-Oh-Nine. Twenty-Oh-Nine! Twenty-Oh-Nine!!"

At which point older son looked around the door and said: "Quite correct."

It was in fact 20:09 20/09/2009

Now what were the odds of that happening?
I accept that older could have been aware of the possibilities of the date and was waiting for the opportunity to use it. But honestly, I didn't.
