[Pw_forum] three times nothing :-)

[BARRETEAU Cyrille]

Dear Paolo,

There is a famous french humorist (Raymond Devos)
who made an whole sketch on this "trois fois rien" he said that
"trois fois rien c'est déjà quelque chose!"
"three times nothing it is already something":-)
Maybe it does not apply to this situation!

in French, there is a nice way to say that something is negligibly  
small:
"c'est trois fois rien" = "it is three times nothing". It perfectly  
describes
the above situation :-).
