I sat down just now to pay the kids their weekly allowance, but my mind was only halfway there. The kids get half their age (in dollars) per week, but simultaneously remembering the ages of four children and then dividing by two was simply too much math at the end of this long day.
Me: Stephen, remind me, what's your allowance?
Stephen: [Eyebrows raised in great hope, and not a moment's hesitation.] $520.
Me: Oh really?
Stephen: Yep, $520.
Me: Per week?
Stephen: Yes. You see, there's this new, um, metric system. And...um...well, $100 is the new $1, so if you convert it over, it means that $5 really equals $520. Except really it's $500, but I'm just throwing in a little tax.
Big points for creativity, anyway. (But still only $5 for allowance).
