Hunger Games and Unintended Puns?

I just finished reading the very engaging novel The Hunger Games, by Suzanne Collins, on my Amazon Kindle. You won't find a review or summary here, though maybe I'll branch into blogging about such things in the future. Click here for the book's Amazon page.

Instead, as befits the intent of our subject material, you'll find a couple of possible unintended puns, which will give you a hint at the book's contents. They'll also give us a chance to think about a published author's word choice, and her editor's missing the pun and/or leaving it in the book on purpose. Discussion below.

The Hunger Games, Chapter 6, by Suzanne Collins. The narrator and another character had worn costumes that imitate fire during the Opening Ceremonies of the Hunger Games. Then during a replay of the procession, she notes: “A few of the other couples make a nice impression, but none of them can hold a candle to us.”

The Hunger Games, Chapter 21, by Suzanne Collins: “I've nine arrows left in all. I debate leaving the knife with Peeta so he’ll have some protection while I’m gone, but there’s really no point.”

The first pun is beautifully subtle. Context: Before the Opening Ceremonies, the characters had worried that when their costumes were "lit" to give them the ultimate effect of looking like fire, the costumes would in fact consume them in real fire, that their fashion designer was a maniac bent on watching them die before the Games even began. Turned out that it was some sophisticated chemical that didn't produce heat. Then, as they watched the replay, the author has the narrator say something so perfect, so appropriate--if the other characters, who will soon be their competitors in the Games, had indeed lit a candle to them, maybe they really would have died in flames, intead of just looking like they were flames.

The second one, more straightforward, nonetheless has a nice twist. For Peeta at this time in the plot, is unable to defend himself, so in fact a knife, which has a point, would have no point for him. And the arrows never would have a point for him, though of course they have a point, because he does not know how to use the bow that would make them a truly useful weapon.

What do you think? Do these particular word choices seem to be on purpose?
Do you know of other Unintended Puns, especially good, subtle, multi-layered or multi-modal ones, that sneak into books?

Let us know.
