Another Blonde Joke...

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 textures, prints and hues of pink fabrics.  Once she has finally picked out a pink floral pattern, the salesman asked her "What sizes do you need?" 
She replies "15 inches."
He exclaims "15 INCHES?! What room are they for?" 
She says, "I only need one, and it's not for a room.  It's for my computer monitor."
The surprised salesman exclaims, "Miss, computers do not have
curtains."
The blond says "HELLOOooooooo...I've got Windows..."
