“People say that money is not the key to happiness…”

“People say that money is not the key to happiness, but I always figured if you have enough money you can have a key made” is a classic line from American comedian, actress and television host Joan Rivers (1933-2014). The quotation was cited—unattributed—in two 1990 newspapers. Joan Rivers was credited with the quote in print by at least 2002.
