- Could you make a torpedo, Mr. Allnut? Well, do so, Mr. Allnut.
- Me, Miss? I didn't say nothin', Miss.
- Eh, it's just this old boiler, Miss. She's leaking' steam. See?
- Oh.
- Uh, why are you kicking the boiler, Mr. Allnut?
- Heat pump's full of rust and scum. She gets clogged up.
- And that's all you have to do? Just kick it?
- Ha ha ha! It's knowing' how to kick her, Miss.
- She gets peevish now and then... ever since I dropped a screwdriver down the safety valve.
- What would happen if you didn't kick it?
- Then why don't you dismantle the safety valve and remove the screwdriver?
