5. Pizza "Pi" Cutter: "Cut your pie with Pi," suggests Think Geek. "For such an irrational number, you sure are kind. You help us do all sorts of things — like figure out the area and circumference of our pizza. And now, with the power of future technologies, and combining things with other things, you will also be able to cut our pizza into pieces." We couldn't have said it better ourselves. If you you know a pizza lover who also appreciates the power of Pi, it's likely well worth the $15 to order them this cleverly make cooking utensil.
