It was in one of my SR3 or maybe even SR2 books. Someone went on a hilarious conspiracy theory rant for about half a page in the Shadow comments before he got cut off in mid-word, and the next Shadow comment was Captain Chaos saying "Good night, <name>". It wasn't Dragonslayer, I remember that much.

Anyone have a clue which book that was?

I'd like to know as well.

Rings a bell, perhaps Cyberpirates? Hm, or older, Denver or Seattle SB...

Yeah, it's Cyberpirates, pg 135.
the poster is named TomTom.

immediately following is the laughing man's famous "house of cards" line.

That was it! Thanks!
