QUESTIONS: While we pondered a random question recently — when you cut a sandwich in half, is it half a sandwich or simply a sandwich of a smaller size, because all the ingredients remain — we were led to ponder the existence of unanswerable questions.

All of these were from Parade Magazine. And now our heads hurt.
