A woman with blonde hair walks into an electronics store...

And gestures over a store employee.

"I want to buy this TV." She said.

The store employee replies to her, "I am sorry, ma'am. But we don't sell TV's to blondes. Store policy."

The woman is visibly upset, but formulates a plan. She goes home and she dyes her hair the most beautiful shade of chestnut brown. The next morning, she returns to the store, and says to the store employee, "I want to buy this TV."

The employee says, "I am sorry, ma'am. But we don't sell TV's to blondes. Store policy."

The woman is a little shocked but is determined. She goes back home and dyes her head a fiery shade of red. The next morning, she returns to the store and says to the store employee "I want to buy this TV."

The employee replies, "I am sorry, ma'am. But we don't sell TV's to blondes. Store policy."

The woman is livid now, but leaves the store. In her rage, she shaves all of her hair off, confident that if she had no hair at all, the store employee would surely not know.

She returned to the store the next morning and said to the employee, "I want to buy this TV."

The employee replied, "I am sorry, ma'am. But we don't sell TV's to blondes. Store policy."

The woman explodes in anger, "How do you know I am a blonde? I don't have any hair!"

The employee smirks a little and says "Well ma'am, it's because that is a microwave."
