Happy pi Day

I looked all over today trying to find a good "Happy Pi Day" card but found nothing. If the bossman is reading this, I think we should shoot for a whole nother level of clientele --the top 1% of the country. Sure they only make up 1% of the country, but where are our astronauts, nuclear physists and listeners of NPR going to buy their cards? Right here baby! That's right. You know why? Because we speak their language.

Here's what I got so far?

(Outside of card we write)

Got pi?

Inside

Happy March 14

or maybe

pi r2? I thought pi were round! Happy 3.14 day!

Simply brilliant.
