How To Replace Mouse Balls
I don't know how they wrote this with a straight face. This was a real
memo put out by one of IBM's engineers 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.

Re: 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.
