One day a blonde was in a store, and saw a sign advertising a huge TV sale. She goes up to the salesman, and points to a shelf and says, “I want to buy that TV.”
The man says “No.”
The blonde, assuming its because he hates blondes, goes home and dyes her hair brown. She goes back to the store and asks again, only to again be told again, “No.”
She goes home dies her hair black, and returns yet again. She asks for the TV, and is told “No, go home you blonde!”
So she finally snaps and cries, “I’ve died my hair twice!How the hell do you know I’m blonde?”
The salesman replies, “That’s a microwave.”
