Balivernes!

l'avenir (masculine) = future
appartenir = to belong to
se lever = to get up
tôt ('t' is silent) = early
ceux ('x' is silent) = those
L'avenir appartient à ceux qui se lèvent tôt = "the future belongs to those who get up early", literally

Which makes me think of these two:
(une) foutaise and (une) baliverne = nonsense, almost always plural as far as I can tell
C'est des foutaises! = This is nonsense!
BALIVERNES! = NONSENSE!
