N is for Nineteenth Century Times Arrow. Captain Picard, Riker, Troi and Geordie travel back in time to rescue Data. I've pieced together an amusing gag gif with Jerry Hardin (born 1929) aka Mark Twain the writer caught red-handed by Data and Guinan. Twain has a lot of fast talking to do only it isn't flying. Data displaced in time is trying to get back to the USS Enterprise NCC 1701-D with Guinan's (Whoopi Goldberg) help and Twain is onto them.
DATA: In a sense. The time shift is a gearing system I have invented for the horseless carriage.
CLEMENS: Hogwash!!! Do not insult me. You have come here to this century and brought your infernal technology with you for God only knows what purpose, but I have no doubt it will be the people of this century who will suffer for it.
GUINAN: My dear Mister Clemens, I do think we've heard enough. Mister Data's business is his own, and I will thank you to leave now.
CLEMENS: Pardon me, Madam Guinan, but it is my business too. It is the business of all humanity, I believe, to stop both of you from whatever it is you are doing here. And that is what I intend to do.
