Today, July 22, I made a pineapple upside down cake to celebrate a particularly 'geeky' holiday. Then, I challenged the kids to figure out what the occasion was and why I was making cake. It took a little while (and some mighty quick Goggling ) but someone finally figured it out.

(The artist, of all people. Go figure.)

**So what's the occasion?**

July 22 or 22/7 is Pi Approximation Day.

**Why cake?**

It's an approximation of Pi (Pie)

And to finish the event is fitting style, how about a geeky pi joke:

Mathematician to Baker:

*Pi r squared*Baker to Mathematician:

*No, pie are round. Cake are squared!*

I thought Pi day is 3/14 at 1:59 pm! However, I like the pineapple upside down cake for pi approximation day! :-)
