One (of many) thing I really like about DS9 is the episode titles, which are generally much more original then thoise of the other star trek shows. A few favourites of mine:"Inter Arma Enim Silent Leges", "If Wishes were Horses", "Through the Looking Glass", "Doctor Bashir, I presume", "Who Mourns for Morn?", "Wrongs darker then death or night", "Treachery, Faith, and the great river", "Badda-bing, badda-bang" and "The changing face of evil"
What titles are your favourites?
