Pi-day promo pricing propels pies

In school, Ad Nut learned that pie are square. Or something like that. It never made much sense, to be honest, because as any fool can tell you, pie are round. Except at McDonald's, where they are rectangular. 

Anyway, a lot of geeky people celebrate something called 'pi day' on 14 March. And because of this, McDonald's Hong Kong and DDB Group Hong Kong devised a promotion to sell pies for HK$3.14 (US$0.40), which you have to admit is cheap, even if you're mathematically challenged.

Pie buyers got stickers that carried a QR code that led to a site where they could create happy messages about their pie-consumption experience to share with friends. Which apparently worked, as the brand claims pie sales shot up by 963 percent on the day.

Ad Nut makes no apologies for being a bit unclear on mathematical concepts (isn't it enough that a humble woodland creature learned to read and write?). Nonetheless, Ad Nut believes that 'pi' day should have been celebrated only once: in the year 15, at 9:26 and 53 seconds in the morning.
