a fireman's doughnut (a doughnut of which the diameter of the circle fits in thecircumference of the circle 3.13159... times)
This one is a little odd, but let me explain it. I had just finished with Toileu which, at least I think, has something or another to do with a strange number. I guess my next thought was about how a baker's dozen is actually thirteen doughnuts. Then I thought to myself: "I can probably make something up off of that." So I thought of another carreer and put it down, but somewhere along the way, I confused "dozen" with "doughnut", and above is how it came out. I like it anyway.
