I Want to Buy that Cupboard

A blonde goes into a nearby super store and asks a clerk if she could buy the cupboard lying in the corner.
The clerk looks at her surprised and says that this store doesn't serve blondes, so she goes back home and dyes her hair red.

The next day she returns to the store and asks the same thing, and again, the clerk says that this store doesn't serve blondes.
Frustrated, the blonde goes home and dyes her hair yet again, to a shade of black.

Sure that a clerk would sell her the cupboard this time, she returns and asks a different clerk this time.
To her astonishment, this clerk also says that this store 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 cupboard -- it's a fridge!"
