Guy: Were you followed? Who is that?
Mulder: It would be a helluva twist if it was Rod Serling.

Move along, sugar boobs, this is The X-Files, no women allowed.

Reggie

Do you know who I am? I'm Fox Mulder. I was fightin' the power and breakin' conspiracies before you saw your first camp trail, you punks! I'm Fox freakin' Mulder, you punks! I'm Fox Mulder! FOX MULDER!!

Mulder

I want to remember how it was. I want to remember how it all was.

Scully

Reggie: When I went back, they had silenced him. They had impaled him with a lawn dart.
Scully: I'm sorry, but what's a lawn dart?
Reggie. Oh! It's this kids' game where you would try to throw these mini metallic javelins into the air into these rings that you put on a lawn.
Scully: And they sold these to kids?
Mulder: We were made of sterner stuff back then, Scully.
Scully: Well, it just sounds like an accidental death to me.
Reggie: NO!!! No! That's what they want you to believe!

Where the hell they takin' Reggie?!

Skinner

I think you just like saying 'Squatchin'.

Scully

Scully: Maybe it's another show, like the Outer Limits?
Mulder: Confuse the Twilight Zone with Outer Limits? DO YOU EVEN KNOW ME???

Mulder: It's the Mandela Effect.
Reggie: The what?
Mulder: The Mandela Effect, when someone has a memory that doesn't coincide with everyone else's or the facts, so named because some people have a memory that Nelson Mandela died in prison in the '80s when in fact he died a free man in 2013.
Reggie: No. It's called the Mengele Effect because people have the memory of Josef Mengele being apprehended in Ohio in 1970, so it's the Mengele Effect.
Mulder: The Mandela Effect has been an internet meme for almost a decade. It's ALWAYS been called that.
Reggie. Eh, see? You're having a Mengele Effect about the Mandela Effect.

Scully: Are you that guy that met with Mulder last night?
Guy: What gave it away, Sculls?
Scully: He mentioned the forehead sweat.

Dr. They: You know, our current president once said something truly profound. He said, "Nobody knows for sure."
Mulder: What was he referring to?
Dr. They: What does it matter?

It's not about the episode, Scully. It's about my memory of seeing my first Twilight Zone. It changed me. You don't forget that.
