I thought this was pretty funny. This is a true IBM ordering
information quote from one of their catalogues. Pass it on...

This is an actual alert to IBM Field Engineers that went out to
all IBM Branch Offices. The person who wrote it was very
serious. The rest of us may find it rather funny.

Abstract: Mouse Balls Available as FRU (Field Replacement Unit)

Mouse balls are now available as FRU. Therefore, if a mouse
fails to operate or should it perform erratically, it may need a
ball replacement. 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 manufacturer of the mouse. Foreign balls can be
replaced using the pop-off method. Domestic balls are replaced
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 replacer have a pair of spare balls
for maintaining optimum customer satisfaction. Any customer
missing his balls should suspect local personnel of removing
these necessary items.

To re-order, specify one of the following:

P/N 33f8462 - Domestic Mouse Balls
P/N 33f8461 - Foreign Mouse Balls
