I just read them in order, last one so far was The Little Gods. And .. I don't know, it didn't click for me.

But I'm really confused about the last line. If it's a quote, I don't know it. I don't speak that language. Google Translate makes this even _more_ confusing.

Given the prominent position (final line of the story) I assume this is important and I feel like everyone is laughing but I don't get the punchline.
