Happy Pi Day

Today is a great day, 3/14.  Known as Pie Day.

But also it's Learn About Butterflies day, so a pie with butterflies.

And it's National Potato Chip Day so how about a pie from potato chips!

Potato Chip Pie from OH Bite It

And because it's technically Pi day, a mathematical reference, we should acknowledge it's also 

Albert Einstein's 138th birthday.
