A plane is on its way to Houston when a blonde in economy class gets up and moves to the first class section and sits down.

The flight attendant asks to see her ticket. "You paid for economy," the attendant says. You'll have to go and sit in the back."

The blonde shakes her head. "I'm blonde, I'm beautiful. I'm going to Houston, and I'm staying right here."
The flight attendant goes into the cockpit and tells the co-pilot that a
blonde bimbo sitting in first class belongs in economy and won't move
back to her seat.
The co-pilot approaches the blonde. "Look," he says, "you only paid for an economy ticket -- you'll have to return to your seat."

The blonde crosses her arms over her chest. "I'm blonde. I'm beautiful.
I'm going to Houston and I'm staying right here."
The co-pilot returns to the cockpit. He says to the pilot, "That woman
won't listen to reason. We should have her arrested when we land."
"You say she's a blonde?" the pilot asks, "I'm married to a blonde. I speak blonde.
I'll handle this." The pilot goes over to the blonde and whispers in her ear. Her eyes grow wide.
"Oh, I'm sorry" she says. She gets up and moves back to her seat in the economy section.
The flight attendant and co-pilot are stunned and ask the pilot what he said to make her move without any fuss.
"I told her first class isn't going to Houston."
