Apple's Grade in English: A-

This Article on Yahoo! News details what hackers find when they attempt to put OSX on a generic x86 box:

The maker of Macintosh computers had anticipated that hackers would try to crack its new OS X operating system built to work on Intel Corp.'s chips and run pirated versions on non-Apple computers. So, Apple developers embedded a warning deep in the software — in the form of a poem.

...

The embedded poem reads: "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."
