1) To have a BIG cockroach fly in just before the lift door closes on you, and you've already pressed the button for your floor. The cockroach then proceeds to fly within the lift.
2) To have a stomach ache while you are driving and you're 10 minutes away from home. But there's no petrol kiosk to zoom into. Whatever it is that needs to come out IS threatening to come out.
3) You're driving and a BIG lizard drops down from no where on your dashboard, threatening to run down towards your hands/lap etc.
