Seegson androids, the Working Joes are pure comedy gold. Of course they are creepy as hell, no denying that, but I just love their lines, especially when they encounter Alien, they go like "what are you?" or "unidentified species". I also love "synthetic's day is never finished" or "I'm not going anywhere, you might as well show yourself" or "returning to assigned tasks" or "I will get to the bottom of all of this". There are many, many others, and they really have a huge repertoire of reactions - in fact I haven't heard all of them as I've seen some of the lines I've never come across on SEGA forums.
