The X-Files, Season 6

Mulder:
Crump? Crump, what else can you tell me about what's happening to you?

Crump:
Mr. Crump. You call me by my last name, you say "mister" in front of it.

Mulder:
"Mister." I got you.

Crump:
Not Crump. Mr. Crump.

Mulder:
I can think of something else I'd like to call you. I could put "mister" in front of that, too if you'd like.

Crump:
You know, what kind of name is Mulder, anyway? What is that, like... like, Jewish?

Mulder:
(disbelieving) Excuse me?

Crump:
Jewish... It is, right?

Mulder:
(annoyed) It's Mr. Mulder to you, you peanut-picking bastard. Now, Mr. Crump what can you tell me about what's happening to you?
