It's Girl Scout cookie season again. The big problem with Thin Mints is that they're just small enough that you can eat "some". If they were any larger, you'd be thinking "1st cookie" "2nd cookie" "third cookie" etc. With Thin Mints, you plan to eat "some". But "some" is an undefined term, and has no upper limit. And that's why I'm sitting here with an empty box.
