A blonde walks into an appliance store and asks the owner, "How much for this TV?"
The owner looks at her and responds, "Ma'am, we've had a history of problems with blonde customers. Therefore we exercise our right to refuse service to anyone, specifically blondes."
The woman stomps out in a huff. She goes to a wig shop and gets a black wig. She puts on the wig and returns to the appliance store and asks the owner, "How much for this TV?"
The owner responds again, "Ma'am, we've had a history of problems with blonde customers. Therefore we exercise our right to refuse service to anyone, specifically blondes."
The woman stares at him, and finally says, "Well, I'm not a blonde. I have black hair. See?"
The owner looks at her, and says, "Ma'am, I know you have blonde hair."
The woman tears off the wig and demands, "How did yu know? Was my hair showing through the wig?"
"No ma'am," the man responds. He points to the appliance the woman is holding, "But that's a microwave."
