There's a verse to hackers hidden inside Mac OS X.
The existence of the lines was originally identified by developers working as part of the OSx86 Project, which is trying to ensure Mac OS X can work on non-Macs.
The 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."
