"Blonde on a plane" joke

There was this blonde who bought a coach ticket to go to Chicago.
She boards the plane and sits in the first class area.
The stewardess comes over and says "ma'am your ticket says coach you must move to the coach area".
The blonde says "I'm blonde beautiful and going to Chicago".
The stewardess says "you must move to the coach area".
The blonde says "I'm blonde beautiful and going to Chicago".
The stewardess goes over and gets the head stewardess. The head stewardess comes over and says "ma'am you must move to coach."
The blonde says "I'm blonde beautiful and going to Chicago".
The stewardesses look at each other and decide to go get the captain.
The captain comes over and says" ma'am your ticket says coach you must move to the coach area".
The blonde says "I'm blonde beautiful and going to Chicago".
The captain shakes his head and bends down and whispers in her ear.
All of a sudden she jumps up grabs her luggage and goes over to the coach area.
The stewardesses look at each other and ask the captain "What did you say to her?"
The captain says " I told her first class wasn't going to Chicago."
