My teenagers' packed lunch. Take one piece of Mothers Pride style bread (naturally, she can't stand all that organic seeded stuff I give her). Spread butter then black olive tapenade (you can take the girl out of France but you can't take the French out of the girl).
Put white foundation on your face. Dye your hair black. Shade eyes thoroughly with black eye makeup. Wear black clothes and hostile expression. Et voila! You are ready for school.
