Dave put characters from Kris Straub's "Starslip Crisis" [starslip.com] in his strip this week. Saturday's "Evil Inc." [evil-comic.com] by Brad Guigar shows one of his characters apparently surfing to sheldoncomics.com on company time...

Not sure if the inserted Sheldon screenshot is courtesy of Brad or if it was done by the colorist Ed Ryzowski.
