You can’t take it with you
Your Guess Is as Good as Mine
You can’t have your cake and eat it too.
You can catch more flies with honey than with vinegar.
You can’t win them all.
You can’t make an omelet without breaking eggs.
You can’t teach an old dog new tricks.
You can’t fit a round peg in a square hole.
You show me the man and I’ll show you the rule.
You can say that again
