I think he said that his comics were like his children, and coming across one online was like getting a phone call at 3AM, and hearing, "Hi, dad! Guess where I am?"
"Hello dad, I'm in JAIL!! I'm calling you from JAIL!! Yeah, throw away the key, I'm in JAIL!! I'm gonna stay here! I like it here! AH-HA-HA-HA-HA-HA!!!!"
But yeah, I'd understand that, from the uneasiness that it could be anywhere. Though in this case it could be assumed that the Far Side comics usually appear when sophisticated humor is desperately needed (for times when the conversation isn't too technical to be interrupted by an xkcd comic). It's not like you're going to see it on an unsavory site. ...right?
*does search* okay, The Far Side is safe from furries, for now.
