Today's xkcd has reminded me of a couple of sideplots from one of the webcomics I've read, which center around the quote "I am a good robot". One involved a pair of planetary-exploration robots, one of which is about to be destroyed and (spoiler) ends up being 'caught' by the other... another involved an interstellar probe, just after launch, encountering something that damages its memory and renders its original course unviable, requiring reprogramming with part of another robot's software; with the last line being something like, "But I like stars /more/!"
I could have sworn that they were from Freefall, but after skimming through the archive, if they're there, I've entirely missed them. Perhaps they're from another webcomic entirely?
Does anyone have any idea what it is I'm actually referring to?
