I found the most unintentionally memorable quote for me to be pretty much everything the chinese soldiers said in Fallout 3, which I can not properly quote, as I do not speak Chinese.
There was also an instant where an NPC used the "He must be out to meet a lady!" line. It probably would have been much less impactful if it wasn't a Follower of Romulus who was watching me escape inside of a catacomb, after I just killed eight of his friends.
