There’s a blond…

There’s a blond and a brunette in a car. The brunette is driving while the blonde is in the passenger seat. They’re going down a steep hill when the brunette realizes that the brakes don’t work. The brunette tells the blonde that the brakes don’t work and they will drive off the side of the cliff because they failed to stop. The blonde then replies, „Don’t worry! There’s a stop sign ahead.“
