A blond walks into an appliance store, walks over to a display, and says to the salesman, "I want to buy that television."

The salesman replies, "I don't sell to blonds." She walks out in a huff.

The next day, the blond returns, goes over to the same display and says to the same salesman, "I want to buy that television."

Again, the salesman tells her that he doesn't do business with blonds, and she again walks out in a huff.

The next day, she dons a black wig and goes back to the store, walks up to the salesman, and says, "I would like to buy that TV."

He says, "I don't do business with blonds."

She says, "I'm wearing a wig. How do you even know I'm a blond?"

He says, "Because that TV you've been trying to buy is a microwave."
