ST:TNG:03 - "The Naked Now" (Stardate: 41209.2) - the 3rd episode in the series (if you consider the pilot "Encounter At Farpoint" being a 2 part episode), this is one of those crossover episodes from the original series to bring a sense of "Star Trek" to this new series. In this episode, the crew becomes infected with a intoxicating element as it happened in the original series aboard Kirk's ship in the 1966 episode "The Naked Time". You get to see the characters, well, OUT of character (to see how a conservative Picard let's down his emotional defenses, i.e. expressing his love for Dr. Crusher - which will become a key focal character interaction as the series progresses). Oh and look out for the "interaction" between Data and Tasha - an event that Data will recount during his discussion 9 years later with the Borg Queen in Star Trek: First Contact!
