The song playing during the scene where Leland dances with the photograph of Laura is Pennsylvania 6-5000 by Glenn Miller.
In the Tibetan map scene, we can see that the letters R and T appear on the blackboard, although Cooper never mentions them. These letters refer to what was found beneath the fingernails of the two murder victims, Laura Palmer and Theresa Banks.
When Cooper turns the Tibetan map over, we see a blackboard with the letters R and T appearing, uncircled. The camera briefly cuts to Truman and company. When the camera returns to Cooper, the R and T are now circled in chalk yet Cooper has not yet picked up the chalk.
We have our first look at "Invitation To Love" the mock soap opera that will often be shown playing on character's televisions throughout the series. In this episode, Shelly sees the title card for "Invitation To Love" before switching off her television.
This episode takes place on: Saturday, February 25 - Sunday, February 26
In the scene where Albert Rosenfield arrives in Twin Peaks, we can see that Lucy is reading a book about Tibet. Earlier in the episode, Cooper has given a long speech about the country.
GOOF: Near the end of the episode, Catherine says to Pete: "What did that FBI man want today?". However, it is now Sunday night and Cooper visited with Pete the day before. This is a mistake in the editing. The scene was scripted to appear in the first act of the show (Which takes place on Saturday night).
Leland Palmer: We have to dance for Laura!
The Man From Another Place: She's my cousin... but doesn't she look almost exactly like Laura Palmer?
Albert: What the hell kind of a two-bit operation are they running out of this tree house, Cooper?
Cooper: Albert, this is Sheriff Truman.
Albert: I have seen some slipshod backwater burgs, but this place takes the cake.
Audrey: Do you like coffee?
Donna: Yeah, with cream and sugar.
Audrey: Agent Cooper loves coffee.
Donna: (smiling) Audrey!
Audrey: But Agent Cooper likes his coffee black.
Cooper: Following a dream I had three years ago, I have become deeply moved by the plight of the Tibetan people, and have been filled with a desire to help them. I also awoke from the same dream realizing that I had subconsciously gained knowledge of a deductive technique, involving mind-body coordination operating hand-in-hand with the deepest level of intuition.
(Cooper takes a big sip of coffee and then quickly spits it out)
Cooper: Damn good coffee! And hot!
Log Lady intro: Sometime ideas, like men, jump up and say 'hello'. They introduce themselves, these ideas, with words. Are they words? These ideas speak so strangely. All that we see in this world is based on someone's ideas. Some ideas are destructive, some are constructive. Some ideas can arrive in the form of a dream. I can say it again: some ideas arrive in the form of a dream.
The One Armed Man: Through the darkness of future's past, the magician longs to see. One chants out between two worlds... "Fire... walk with me." We lived among the people. I think you say, convenience store. We lived above it. I mean it like it is... like it sounds. I too have been touched by the devilish one. Tattoo on the left shoulder... Oh, but when I saw the face of God, I was changed. I took the entire arm off. My name is Mike. His name is Bob.
Man From Another Place: I've got good news. That gum you like is going to come back in style.
Cooper: (On the phone) Harry, it's Cooper. Meet me for breakfast, 7am in the hotel lobby... I know who killed Laura Palmer. No... it can wait till morning.
So intense was the interest in knowing who killed Laura Palmer, that people would go through the trash outside the studio looking for discarded script pages.
Be advised that the DVD commentary for this episode contains a spoiler as to the identity of Laura Palmer's killer.
The 'Red Curtain' scene is parodied in The Simpsons seventh season premiere 'Who Shot Mr Burns Part 2', when Lisa comes to Chief Wiggum in a dream to tell him how to progress in his investigation.
Instead of the usual closing credits shot of Laura's prom photo, this episode uses an overhead shot of the Man from Another Place dancing to his dreamy theme music.
The bizarre sounds and movements made by the Man From Another Place and Laura Palmer in Cooper's dream were achieved by having the actors speak and move backwords. Lynch then reversed the film so everything seemed to be moving forward.
Episode 2 was nominated for two Emmy Awards in 1990. One for Badalamenti's score, and one for Sherilyn Fenn.
A.K.A. "Zen, or the Skill to Catch a Killer"

The title is an allusion to Robert M. Pirsig's novel Zen and the Art of Motorcycle Maintenance, itself a play on the title of the book Zen in the Art of Archery.
One Eyed Jack's
A crude phallic reference in keeping with the nature of this particular establishment. The character of Bobby Peru in Lynch's Wild At Heart also uses this term with the same meaning.
