Quote context

[...]

- I hated to lose that ray gun, but it would only have been good for a few shots without another charge of lunarium.

- And now that we have a lunarium, we can build our own ray guns and pistols.

- Yes. We brought back one of their ray pistols.

- Looks fairly simple.

- Yes, would you like me to take it apart to show you how it works?

- Please.

- There's the intake for the air conditioning system. Put the hose in and turn the gas on.

- Let's find a spot where we can watch the window in case anyone tries to get out.

- We must start manufacturing these weapons at once.

- Wouldn't it be better to save the lunarium for bigger guns? They're what we'll need to stop an invasion by rocket ships.

- Excuse me, but isn't getting awfully stuffy in here?

- I'll open a window.

- You better get her out of here, Mr. Henderson.

- It won't open!
