Subject: Replacement of mouse balls

I don't know how they wrote this with a straight face. This apparently
was a real memo sent out by a computer company to its employees in all
seriousness.. It went to all field engineers about a computer peripheral
problem. The author of this memo was quite genuine. The engineers rolled
on the floor! Especially note the last couple of sentences.

Replacement of Mouse Balls.

If a mouse fails to operate or should it perform erratically, it may need
a ball replacement. Mouse balls are now available as FRU (Field Replacement
Units). Because of the delicate nature of this procedure, replacement of
mouse balls should only be attempted by properly trained personnel. Before
proceeding, determine the type of mouse balls by examining the underside
of the mouse. Domestic balls will be larger and harder than foreign balls.

Ball removal procedures differ depending upon the manufacturer of the
mouse. Foreign balls can be replaced using the pop off method. Domestic
balls are replaced by using the twist off method. Mouse balls are not
usually static sensitive. However, excessive handling can result in
sudden discharge.

Upon completion of ball replacement, the mouse may be used immediately.
It is recommended that each person have a pair of spare balls for
maintaining optimum customer satisfaction. Any customer missing his balls
should contact the local personnel in charge of removing and replacing these
necessary items.

Please keep in mind that a customer without properly working balls is an
unhappy customer.
