A blonde woman walks into an appliance store and begins browsing. She points to an item and asks the clerk, "Can I have that television set over there?"
The clerk looks at her and says, "No."
Confused, she asks, "Why?"
"Because you're a blonde," the clerk replies.
The woman leaves but soon returns with an idea. She is now wearing a red wig. She asks the clerk again for the same television set.
He looks at her suspiciously and says, "No. I told you I don't sell them to blondes."
"But I'm not a blonde," she insists. "I'm a redhead."
The clerk then replies, "I know you're the same woman. That's not a television; it's a microwave."
