Very well then, here comes someone, as it might be me, and stands as it might be here, and says to that lamp, as I might do, collecting all my willpower: Lamp, turn upside down in mid-air without breaking and go on burning steady.

Quote context

[...]

- What we have here is swinging from the ceiling a paraffin lamp, or perhaps I should say a kerosene lamp. Either way, we can agree to call it an oil lamp. Is that right?

- Yes, that's right.

- Well, now let me show you what I mean by a miracle.

- That oil lamp, in the course of nature, couldn't turn upside down and keep on burning, could it?

- Oh, you say it couldn't.

- Well, could it? Never mind what I say, what do you say?

- Er, no, it couldn't.

- Of course it couldn't.

- If the lamp turned upside down, it would go out in the course of nature. Any oil lamp would.

- Very well then, here comes someone, as it might be me, and stands as it might be here, and says to that lamp, as I might do, collecting all my willpower: Lamp, turn upside down in mid-air without breaking and go on burning steady.

(woman screams)

- It's going to fall!

- I can't keep it up, my willpower, any longer.

- George, you ought to be ashamed. What do you think you're playing at, coming in here and playing tricks like that?

- This is a respectable house, and we don't want anything like that in it. Conjuring tricks.
