Woman: I can't get the arrow on my computer to move.
Techie: Do you have a mouse?
Techie: Then move your mouse up and down.
Woman: I am!
Techie: And what happens?
Woman: Nothing! The arrow still doesn't move!
Techie: I'll be right over.
When the computer techie arrives, he asks the beautiful blonde to demonstrate exactly what she had been doing.
The beautiful blonde retrieves the mouse from her desk and starts waving it up and down, above her head and down to the desk, over and over.
You see, she cries out to the techie. No matter how many times I move the mouse up and down, the arrow on my computer screen won't budge, not even an inch!
