Kind of a lot of choices, but I have to put it out at some point :)
To my husband (if he dies after me): "Life is nothing without love. Love can be nothing without someone to accompany it. Life is nothing without a point of death. I have lived a well life and I have loved you much. You have been kind enough to return that love and have lived long - longer than I. Live well in remembrance of me."
To my children: "Live long and prosper."
To Shaun White (if he dies after me): "Life is short, and you are hot."
To whomever may be in the room and willing to listen: "Life is merely an entertainment act keeping you busy until it is time to go. Death is merely the symbol of that time. Beyond death, that is what I wonder. No one is perfectly right or wrong of what lies beyond. But if nothing else may be said of this, let this be known: I am going somewhere. No, not to nothingness. But rather to a perfect place I have awaited my entire life. My entire life I was merely stalling time until I could return home."
