From a buddy of mine:

I don't know how they wrote this with a straight face.
This was a real memo sent out by a computer company (IBM) to
its employees in all seriousness. It went to all field engineers regarding
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 .



To whom this may concern 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.
