We have a great saying in German when people are saying or doing something stupid:
“Herr, wirf Hirn vom Himmel!”
“Lord, throw some brains from the heavens.“
fave follow-up: “oder Steine, Hauptsache er trifft.” – “or stones as long as he hits the mark”
Germans don’t fuck about.
my fave follow-up “und mache dass die Idioten es nicht aufessen.” – “and make that the idiots don’t eat it.”
