h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

A very versatile little idiom which means literally you don't have to be a wizard ("sorcier")to manage to do this /it's not rocket science. Most often found with adverbial form "quand même" (after all), like this:
"C'est quand même pas sorcier!"
To be used when deploring others' lack of wits.

As opposed to the wizard in the kitchen "c'est pas saucier"

Sorry coat on, collar turned up, hat pulled right down - never know whether puns work in French, since I only ever heard them made by English people and met with occasional French tittering.

"Saucier" is rare today. Sauce-boat is "saucière".

But since we are on this subject. "se faire saucer" means get drenched by rain.
"Qu'est-ce qu'on s'est fait saucer!" meaning we got soaked through.

Aha thanks, Martine - really hard when the language we learnt thirty years ago was distilled from the language learnt by teacher tewnty years previously..

On the subject of moisture, I /do/ remember a joke in French school text-book on being lost on an outing in wet weather with the punchline "trompé aux os".

Teacher says "trempé jusqu'aux os". I suppose the punchline is about the prononuciation of "os", bone, same sound as "eau" (water) with the s silent .
