Pie or not 2 pi?

Anybody who knows me or my family of mathematicians will know of our recurring quandary - what do you get when you divide a pie (or cake)? Four slices (for instance) each of roughly pi/2, since 360º is 2pi in radians.

So imagine my glee when this morning, over breakfast, The Adventures of Billy and Mandy on Cartoon Network came up with the same problem. We are not the only weirdos on the planet. I went off to work with a little grin - badly misjudging the day ahead...
