Frustrated, the blonde goes home and dyes her hair yet again, to a shade of red. Sure that a clerk would sell her the TV this time, she returns and asks a different clerk this time. To her astonishment, this clerk also says that she doesn't serve blondes.
The blonde asks the clerk, "How in the world do you know I am a blonde?"
The clerk looks at her disgustedly and says:
"That's not a TV... it's a microwave!"
