A friend's sister really is that "dumb blond". She's a nice person and his sister, so we try to keep the mocking to a minimum, but sometimes it's too hard. One day while driving, the following took place.
Ambulance comes up behind us, lights and sirens on. The sister is driving and she slows down in the middle of the lane to about 15 miles an hour. It doesn't take long before a chorus of "pull over!" "what are you doings?" fills the car. Finally the ambulance has the opportunity to pull into the other lane and pass our car.
The rest of us are speechless but her brother finally says "Why the hell did you slow down?"
To which she replies "Can't they give tickets?"
