So she leaves.\nThe next day she dyes her hair brown and goes back to the store. "I'd like to buy that TV over there". The clerk says "No, we don't sell to blondes". So she leaves.\nThe next day she dyes her hair red and goes back to the store. "I'd like to buy that TV over there". The clerk says "No, we don't sell to blondes". So she leaves.\nShe goes back every day with a different hair color, each time getting the same answer. Finaly she asks "How do you know it's me every time?" and the clerk replies "Ma'am, that's not a TV. That's a microwave".
