Apple recently confirmed that the following poem is included in the Mac OS X for their Intel-based computers:

Your karma check for today: There once was a user that whined/his existing OS was so blind/he’d do better to pirate/an OS that ran great/but found his hardware declined./Please don’t steal Mac OS!/Really, that’s way uncool./(C) Apple Computer, Inc.

The poem would become activated if someone attempted to force the OS to run on non-Apple hardware.

It is rather humorous that Apple would try to subdue software pirates with poetry.
