Dumb blonde

A blonde woman goes into a department store and tells the salesman she wants a pair of pink curtains.
He assures her they have a good selection of pink curtains.
He shows her many kinds of different fabrics of curtains and she finally picks out a pink floral pattern.
The salesman asks, "What size do you need?"
She says, "15 inches."
He exclaims, "15 INCHES!.......What room are they for?"
She says, "It's not for a room, it's for my computer monitor."
The surprised salesman exclaims, "Miss, computers do not need curtains."
The blonde says, "HELLooooooo.........I've got Windows!"
