2x15 - Won't Get Fooled Again

Jack: John?
J: (weakly) That's my name. Don't wear it out.
:-) This is a silly thing said by young children or childish adults to annoy someone

Jack: Hey, how you feeling?
J: Hot. Dizzy. Kinda-- feel like I been hit by a house.
Wizard of Oz references abound in this ep, which makes sense. Dorothy was transported by a tornado funnel to the Land of Oz where she didn't fit in. All John needs now is a pair of ruby slippers.

J: (whistles) Won't get fooled again.
Pete Townsend song

J: The Ancients? Nah, they picked my brain already. Maldis? Uh uh. Not Gothic enough. Not his style. (looks at 'Zhaan', smirking with a realization) Delvians. Mm... yeah, Occams Razor... Taleen and her wacky bunch. (in an ‘over the rainbow munchkin' voice) Come out, come out, wherever you are, and see the young man who fell from a star.
Wizard of Oz again... also in this line is the mention of Occams Razor, which is a scientific principle that states when searching for answers the simplest answer tends to be the right one

J: (to Scorpius) Dig your style, Ringo.
Ringo Starr is the drummer for the Beatles.

J: Scorpy. You don’t fit the pattern. You got not Halloween costume, got no assumed name, you’re not playing a role. That suggests something to me. That suggests that you are the man behind the curtain!
John seems to really like Wizard of Oz.

J: Look, somebody is gas lighting me!
Gaslight--great movie

J: So, that’s the play? The play, the play, the play is the thing.
And more Shakespeare...I guess it's all right to quote as long as it's not villains doing the quoting.

J: (squinting through a haze of cigar smoke) I reenact my initial mission. I show you how I create the giant blue twister that sucks me down to Oz!
John is referring to the wormhole that sucked him into the Uncharted Territories, much the same as the twister took Dorothy from her home in Kansas to the Land of Oz in the Wizard of Oz

J: (another weak Elmer Fudd laugh) You’re Harvey? (small laugh) Or is it Clarence? ... Guardian Angel? ... Invisible Rabbit ... (his head bobs back and forth in an internal debate) ... Harvey ... ? (inhales sharply/decisively) Harvey.
Harvey, starring Jimmy Stewart, and Clarence is a reference to another Jimmy Stewart movie....It's A Wonderful LIfe
