* The conversation at the start of the film where Jimmy's brother Michael [[ChildrenAreInnocent keeps asking what an abortion is]], oblivious to the fact he's just let his older sister know that Jimmy's knocked up Ruth.
** A darker example comes a bit later when Jimmy's father is building a makeshift bomb shelter.
---> '''Michael:''' We'll be able to sleep in it! [[InnocentInaccurate It'll be like going camping!]]
* One minor BlackComedy moment. Two soldiers have caught some looters stealing food.
-->'''Soldier 1''': ''[Indicates towards crisps among the loot]'' What flavour are they?
-->'''Soldier 2''': [[StockYuck Prawn Cocktail.]]
-->'''Soldier 1''': Aye, they fucking would be!
* Jimmy's father has the misfortune to be on the lavatory when the bombs start falling, causing him to pull up his trousers with a succinct "Bloody hell!"
* Jane's pierced ears. It's nice to know that even in a post-nuclear apocalypse world, no girl or woman ever goes out without some sort of jewelry adorning them.
* An anti-war protestor gets into an argument with a heckler. "Don't call me unpatriotic! I've been trying to get us out of the Common Market for years!"
** Also HilariousInHindsight considering the UK's recent Brexit decision. [[RuleOfCautiousEditingJudgement And let's leave it at that.]]
* Earlier in the film, it's mentioned in passing that traffic wardens will be conscripted to keep the peace should there be a nuclear attack. Later in the film, four weeks after the attack, there's a detention camp set up for people caught looting the houses of the dead. Who should be guarding the prisoners but [[BrickJoke a traffic warden]]?
** While only bleakly funny, there's a bit of {{Narm}} to one of the prisoners shouting:
---> '''Man:''' I'm buggered if I'm gonna be shot by a traffic warden!
