לא לשים הגמל בזבל (don't put the camel in the trash)
(in Hebrew לא לשים הגמל בזבל): a funny/silly Hebrew phrase meaning, don't do something ridiculous or retarded without having though it through, only to regret it later.
Since camels are a valuable source, even to this day, of transportation in The Middle East, I will conclude that the phrase לא לשים הגמל בזבל (don't put the camel in the trash) in English, would have to be a rational and sound piece of advice, let alone a silly phrase I invented.
