A blonde goes into a nearby store and asks a clerk if she can buy the TV in
the corner. The clerk looks at her and says that he doesn't serve blondes, so
she goes back home and dyes her hair black. The next day she returns to the
store and asks the same thing, and again, the clerk said he doesn't serve
blondes. 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!"
