The X-Files, Season 7

Scully:
You know, Mulder, there's still one thing that you haven't explained.

Mulder:
What's that?

Scully:
How the Amazing Maleeni was able to turn his head completely around.

Mulder:
I don't know that.

Scully:
I do. I'll show you. Observe. (gets down on hands and knees on the floor; Mulder grins. Puts her hands on the floor, turns one hand a full 360 degrees; Mulder is impressed)

Mulder:
Gee! Very nice. How'd you do that?

Scully:
Well... magic. (keeps walking down the hall; he follows)

Mulder:
No. Seriously, Scully, how'd you do it? You know, it's not the same thing. It's different with the head. Come on. Look at this. (does the disappearing thumb trick; she ignores him)
