Shaun of the Dead2004

Ed:
What's going on, Shaun?

Shaun:
[on the phone trying to reach emergency services without any luck] Sh*t. It's engaged.

Ed:
How about an ambulance?

Shaun:
It's engaged, Ed.

Ed:
[after a pause] Fire engine?

Shaun:
[exasperated] It's one number, Ed, and it's busy! Okay? What'd you want a fire engine for, anyway?

Ed:
Anything with flashing lights, you know?

Shaun:
They still out there?

[Ed pulls back the curtains, revealing two zombies scratching at the window]

Ed:
[shuts curtains, steps away contemplatively] Yeah. What you think we should do?

Shaun:
Have a sit down?
