You can’t unscramble a scrambled egg.
Your guess is as good as mine
You can’t make an omelet without breaking eggs.
You can’t fit a round peg in a square hole.
You can catch more flies with honey than with vinegar.
You can’t win them all.
You show me the man and I’ll show you the rule.
You can’t have your cake and eat it too.
Your name is mud
You can lead a horse to water but you can’t make it drink.
