Shaun: Well maybe one should do the other, and then do themselves.
Liz: Oh maybe you should do me, I'll only muck it up if I have to do myself.
[Shaun mimes shooting Liz and then himself, to see how it feels]
Shaun: You know, I don't think I've got it in me to shoot my flatmate, my mum, and my girlfriend all in the same night.
Liz: [pauses] What makes you think I'd have taken you back?
Shaun: Well... You don't want to die single do you?
Ed: [interrupting] That's it. I would like to be shot.
Shaun: Besides, I've changed. I haven't had a fag since yesterday, I promise!
Ed: He hasn't!
