Zazie in the Metro: 20th Century Book

I'm going to hazard a crazy guess as to what this book is really about'besides the immediately recognizable themes which others have analyzed and canonized, themes such as the bizzareries Zazie encounters in the metropolis and the dazzling use of slang in the narrative.

But before I hazard my crazy guess, you'll have to be patient with me while I do a little hypothesizing, while I attempt to puzzle it all out. Because I really am trying to get to the bottom of Queneau's intention here. I'm attempting to look behind the pizzazz of the wordplay, to fully fathom the fundaments of this underground story (and the subversion of language and narrative which characterizes the book, of course).

Tu causes, tu causes, c'est tout ce que tu sais faire!
Chatter, chatter, it's all you know how to do!

You might, at this point, be getting impatient, and inclined to repeat Laverdure's words (Laverdure is a parrot who parrots a perfect parody of both himself and his owner at every turn of the narrative). But I'm not like them, I'm not such a quiz. I really do have something to say if I could only cough it up, spew it out, as it were (ok, sorry for being such a scuzz). But my crazy thesis about this book is buried deep, it really is, deeper than the maze of underground passages through which softly spoken Marceline zigzags in the last pages (and little wonder Marceline speaks softly with a name like that! (and little wonder Marceline is who Marceline is in the first place! (and please excuse all this overzealous parenthesizing))).

Tu causes, tu causes, c'est tout ce que tu sais faire!
Chatter, chatter, it's all you know how to do!

I hear your frustration. Yess, yess, yess (more soft sounds just to say I'm no gongoozler. No, I'm very busy tunnelling down to reach my crazy theory, and the last pages are not irrelevant: 'Last', that whizz of a word, is actually very pertinent to my crazy thesis, viz, the phrase 'the last will be first').

Tu causes, tu causes, c'est tout ce que tu sais faire!
Chatter, chatter, it's all you know how to do!

Ok, I realise I'm in danger of touching hyperboliquement le cercle vicieux de la parabole* so don't get frazzled, I'm going to get straight to the point, no more zig-zagging, no more buzzing about like a zesty scherzo, no more spritzing myself into a dizzy tizzy: Queneau's subversion of the language of narrative, his use of slang, all those run-on words and phonetic spellings, par egzemple: egzagèrer, vouzêtes, etc is his attempt to undermine the established order, to turn everything on its head, to put what comes normally at the bottom on the top.

You knew that all along?
You knew that the clue was in the title?
You knew that it was really about celebrating the last letter of the alphabet?
The letter Z?

Mon cul!**

*a marvelous Queneau phrase that mixes rhetoric and maths and more or less accuses me, and some of the characters, of talking rubbish in a way that is both shallow and deep at the same time - not an easy task, I swear!
**Mon cul is Zazie's favourite swear word. It translates as 'My arse!' if you're Irish, 'My ass!' if you're American, and if you're English...'My bottom'.
