He is no great heir that inherits not his ancestor's virtues

A rich man is either a scoundrel or the heir of a scoundrel

The way to be immortal (I mean not to die at all) is to have me for your heir. I recommend you to put me in your will and you will see that (as long as I live at least) you will never even catch cold.

He is the only heir-apparent. I don't see any negative impact to the share price.

What's ill-got scarce to a third heir descends, nor wrongful booty meets with prosperous ends.
