A: Proofreading.

The Blonde Cop

A blonde in a convertible is speeding down the highway when she gets pulled over by a female police officer, who also turns out to be a blonde. 
She walks up to the convertible and asks to see the blonde's drivers license. 
Confused, the blonde asks, "What does a license look like?" Eager to help, the officer happily responds, "It's that thing in your purse with your face on it." 
The blonde begins searching through her purse and finally pulls out a mirror. She flips it open, sees her own reflection and figures that must be it. 
After handing it over to the officer, the officer carefully looks at it says, "Oh, I'm so sorry. If I knew you were a cop, I wouldn't have pulled you over!"

A Blonde Test

A blonde reports for her university final exam which consists of mainly true and false questions. She takes her seat in the examination hall, stares at the question paper for five minutes, and then in a fit of inspiration takes her purse out, removes a coin and starts tossing the coin and marking the answer sheet: true for heads and false for tails. Within thirty minutes she is all done, whereas the rest of the class is still working furiously.

During the last few minutes, she is seen desperately throwing the coin, swearing and sweating. The moderator, alarmed, approaches her and asks what is happening.

"I finished the exam in a half hour," she replies. "Now I'm rechecking my answers."

The blonde on an aeroplane

There's this blonde.

She gets on a plane and sits in the first available seat. The flight attendant is coming around checking tickets. She looks at the blonde woman's ticket and tells the blonde; "ma'am you can't sit here, your ticket says coach and this is first class. please move to the back of the plane"

The blonde replies "I'm a blonde, I'm smart and have a good job. I'm not moving until the plane arrives in Jamaica"

So the flight attendant, now hot under the collar at the blonde's response, goes to another flight attendant and tells him what happened. so he goes up to her and asks her to move to the back of the plane.

She then responds "I'm a blonde, I'm smart and have a good job. I'm not moving until the plane arrives in Jamaica".

So the two flight attendants are steaming mad and they go to the co-pilot and tells him what is going on. He comes back to where the blonde is sitting and leans over and whispers something in her ear.

The two flight attendants were astonished when the blonde abruptly got up from her seat and moved to the back of the plane. They looked at each other and then the co-pilot and asked him what he told her.

The co-pilot, feeling good about himself told them "oh, this happened a while back with someone else. I just simply told the woman that the front half of the plane wasn't going to Jamaica".
