"The appliance store" joke

This blonde lady walks into a store and goes up to an employee who works there. She says, "Ummm...excuse me. Can I buy that microwave over there?"

The man employee answers, "O sorry. We don't serve blondes here."

So...she goes home, and dyes her hair brown. She goes back up to the same employee at the same store and asks the same question. And she got the same answer back.

So....she goes home and shaves off all her hair. Then for the last time, she decides she'll go back to that store and ask again. "Can I buy that microwave over there?"

The employee answers, "Sorry, we don't serve blondes here."

"Well, how do you know that I am a blonde?" says the blonde.

"Because that's not a microwave. That's a television."
