Measure your cake slice down to the millimeter with this serving plate. As the product description says:

With this plate, the concept of measurement is explored in a way to create a connection between the person and the object. For instance, when cutting cake or cheese, nobody will complain about having the smallest slice.

Oh, I think they'll still complain about having the smallest slice, because now it'll be even easier to tell who does. CAD$45, plus shipping, from uptoyoutoronto.com [via Boing Boing]
