(You) can't take it with you.
Prov. Cliché Since you cannot take your wealth with you when you die, you ought to enjoy it while you're alive. Go ahead, splurge a little while you've got it. You can't take it with you. Henry: Sure, I spent a fortune on this car. Can't take it with you, you know. Rachel: And this way, you can share it with your friends.
