The Young Ones, Series 2

Vyvyan:
"Do not lean out of the window." I wonder why?

[Vyvyan leans out of the window, only to have his head cut off whilst going through a tunnel]

Vyvyan:
Aaaaaaaaaaaaaaaaargh!

[The headless Vyvyan winds up pulling the communication cord, stopping the train]

Rick:
Oh, good heavens, what now?!

Mike:
Somebody must have pulled the communication cord.

Rick:
Well, it wasn't me, matey. If British Rail want 50 pounds, they can just about bloomin' well go out and become a prostitute, which they virtually are anyway, come to think of it... [turns to camera] ...right, commuters?

Neil:
Oh no, we'll never get there on time now!

Mike:
Relax, Neil, Bambi's a personal friend. I introduced him to Walt Disney.

[On the tracks outside, Vyvyan's headless body is stumbling around, while his head shouts at him]

Vyvyan's head:
Over here! Over here! I'm over here, and hurry up about it, will you! [Vyvyan's body stands over his head] You took your time, you bastard!
