I would love to see more Batman Beyond memes. It was a solid show but I don't think they had a better single line than this one though this zinger from old Bruce Wayne might come close. Now that I think about it, the most memable scene in Batman Beyond might be the snippet from this video at 3:07 where some punk teenager dressed in a bad Joker costume unknowingly says to Batman himself. "Who do you think you're talking to old man? We're the Jokerz!" and Bruce sarcastically replies, "Sure you are." The meme would work for every bad remake. "Who do you think you're talking to old fans? We're the Lord of the Rings!" "Sure you are" Anyway, my favorite battle scene in LOTR is this one. Anyway, for those poor sad people who never saw Batman Beyond, the full context for the meme is here.
