A blonde was headed to Detroit. She got on the plane and sat down in first class.
A few minutes later, a flight attendant came up to her and told her that her ticket was for coach and she had to move from the seat. She refused. The flight attendant was persistent, but the blonde replied, "No, I want to sit here, I've always wanted to see what it is like in first class."

The flight attendant was getting frustrated. Finally, after quite some time, she convinced her to move.

Another passenger who overheard the conversation asked the attendant, "How did you get her to move?"

The flight attendant replied, "I told her that first class doesn't stop in Detroit."
