Quote from : The Naked Gun: From the Files of Police Squad! Movie

Driving instructor: It's okay. Normally you would not be going sixty-five down the wrong way of a one-way street.
[a large semi truck appears speeding out of a tunnel towards the car. Stephanie screams, even Frank is terrified, but the unflappable driving instructor continues to remain perfectly calm]
Driving instructor: [continues to talk in a calm, casual tone] Apply the brake.
[Stephanie slams her foot on the brake]
Driving instructor: Now, put it in reverse...
[Stephanie slams her foot on the gas petel speeing in reverse away from the truck now only inches from the car. The driving instructor continues to remain perfectly calm]
