You know what'll just about give you a heart attack and/or make you crap your pants? Driving home, late at night, in the rain, on a dark country road and suddenly seeing two HUGE mo-fo deers in the middle of the road, slamming on the brakes, and stopping about a foot from one of them, while he looks at you like "what the hell are you doing lady this is my road come on now...oh shit....it's not...run run run into the bushes". Yah, that'll just about do it. Almost.
