Red Dwarf, Series IV

[Realising she only has 3 minutes to live after having her IQ upgraded Holly decides to shut off all power, causing concern for the crew]]

Kryten:
Shh. Listen, can anyone hear anything?

Cat:
No

Kryten:
Exactly, no one can hear anything, and do you know why we can't hear anything?

Rimmer:
(annoyed) Why?

Kryten:
(in a spooky voice) Because there are no sounds to hear!

Rimmer:
Kryten, isn't it around this time that your head goes back to the lab for re-tuning?

[The crew are talking about how to go back to the bridge through closed doors.]

Cat:
I've got it. We laser our way through.

Kryten:
An excellent plan, with just two drawbacks: One, we don't have a power source for lasers; and Two, we don't have any lasers.
