SCOping the Source

Webcomic Storyline: 

Kernel Panic, by Christopher B. Wright

Comic Transcript: 

ALAN: Didn't we already talk to SCO? And by talking, I mean throwing a monitor at their sales guy.

JACK: I guess they didn't take the hint.

ALAN: Alright. Give me this letter, and let's see what they want.

ALAN: "Dear Linux Customer: As you know, SCO invented Unix. Because Linux uses aspects of the Unix codebase, you are probably violating our intellectual property. We'd like you to pony up the dough before we set our lawyers on you like a pack of wild, ravenous dogs."

JOHNNY: WHAT shared code?

ALAN: The "n" and the "x," I guess.
