Joe and Kurt

In the May 16, 2005 edition of The New Yorker Magazine, author Kurt Vonnegut told this story of his friend, author Joseph Heller:
Joseph Heller, an important and funny writer now dead, and I were at a party given by a billionaire on Shelter Island.
I said, "Joe, how does it make you feel to know that our host only yesterday may have made more money than your novel 'Catch-22' has earned in its entire history?" And Joe said, "I've got something he can never have." And I said, "What on earth could that be, Joe?" And Joe said, "The knowledge that I've got enough."
