The redhead "schoolgirl" telling Andrew she wants himinside of her. Andy then punches her through the stomach and retrieves his wedding ring she had earlier swallowed.
Oliver's blank reactivating and returning to his estate career, and replacing the upper half of his missing head with a football with marker eyes on it.
Gary being more concerned about spilling his pint than the Bar Brawl going on around him and which he's actively taking part in.
"King Gay!" *giggling*
Steve unabashedly admitting he was the one who scratched out the R.
"Let's get this antique...ON THE ROADSHOW!" The facial expressions on Gary's mates after the punchline is the definition of the Flat "What". Punctuated by each one getting a ring from the 4 o'clock bell.
Andy:[drunk] Gary says that we should keep up with the crawl, because they might know what we're doing. But they don't know that we know what they're doing. And basically, no one else has any better idea...so fuck it. [smashes his hand through glass in the door as he heads out]
Before the beer garden scene outside The Two-Headed Dog, Andy drunkenly says that Gary is probably trying to fuck Oliver's sister when he heads outside, prompting Blank!Oliver to say, "Andy!"
[Four dramatic shots of beer being poured on tap, with suspenseful background music, which cuts off as Andy's water is poured]
Gary: I don't believe this. A man of your legendary prowess drinking fucking...rain. It's like seeing a lion eating some hummus.
Oliver: That doesn't make any sense.
Gary: I know it doesn't make any sense.
After the guys leave The Mermaid:
Steven: They knew these three would fall for a bunch of girls in school uniforms.
Gary: Hey, who wouldn't, am I right?
Pete: Fuck yeah!
[Gary and Pete high-five each other]
Gary and Sam trying to escape. She suggests climbing down the drainpipe while he tries to jump off the roof onto a car. He lands hard on his back and hurts himself before wheezing "Climb down the drainpipe." Not long after:
After the craziness starts to pile up in Newton Haven, former teetotaler Andy decides to neck all five shots in one go. The funniest parts are his ravenous grunting as he takes each one and the stunned reactions of everyone else considering Andy was the only one sober enough to drive back. Not anymore!
The use of The Doors cover of "Alabama Song", as the entire town stares at them trying to act natural.
Steven: You really have a selective memory, don't you?
Gary: Somebody else was saying that!
Gary: No, I would have remembered.
Oliver: Maybe they [the blanks] have selective memories.
Gary: Yeah, like what's his name? [thinking hard]... ME!
Andy, Steven and Peter deciding Gary is the real deal ("It's Gary") after bashing his head repeatedly on a post in the smokehouse, evidently deciding Gary probably wouldn't be that stupid if he was a Blank.
This exchange after Basil explains the Blanks' replacement system:
Steve: What happened to the people who got replaced?
Basil: The Empties? Don't ask me what happened to them.
Andy: What happened to the ones you replaced, like Peter and Oliver? Steven: Yeah! What happened to the Empties?! Basil: (somewhere offscreen) I told you not to ask that!
After The Network leaving the Earth triggers an explosion, the boys ask Basil how to escape:
Basil: Same as before! [starts running in the opposite direction] GO!
Andy: The worst part is I promised myself I wouldn't die in this town.
And then Sam shows up in her car, Gary runs to greet her - and gets hit by the car. Steven joyfully exclaims that she came back for them, to which she agrees...before admitting that she also got lost trying to get out of town.
How did Mad Basil manage to avoid the Blanks' influence? He always drinks from a crazy straw!
After Steve, Gary and Sam fight off the creepy twin robots, they come back to the other three friends still arguing what to call the Blanks, with Andy commenting: "Nothing suggested in the last three minutes has been better than Smashey-Smashey-Egg-Men."
Just to top it, Gary's first comment is asking whether they have come up with a good name.
In the DVD commentary, a Shout-Out is made when David Bradley's character (Basil) reappears in The Famous Cock, looking slightly depressed; in response, Simon Pegg flat out spoils a Game of Thrones season finalé twist, to which Edgar Wright starts cracking up.
