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

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

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?

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!

That's when I dropped out of med school, joined the FBI and created the X-Files. That's right! We used to be partners!!!

Reggie

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

Scully

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

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.

Mulder

Mulder: So that's the truth? We're not alone in the universe, but nobody likes us?
Scully: It's OK Mulder, we'll always have more X-Files.
Mulder: No. They gave us the answers to everything, even Sasquatch! No! It's not true!!

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.

I think you just like saying 'Squatchin'.

The X-Files Quotes

O'Malley: Oh. Those don't roll down. I had the vehicle bulletproofed.
Mulder: Because you never know when a gun-toting liberal might go Hinkley.

Scully: I'm always happy to see you.
Mulder: And I'm always happy to find a reason.
