What sticks with me is his oft-quoted: "Mamma said: 'Life is like a box of chocolates. You never know what you're gonna get.'"
And he never does know. He is the ultimate example of somebody who goes with the flow, so long as it doesn't interfere with his loyalties and principles, which are fierce and fundamental. He never quite realises the incidental impact his actions have on others.
Among other things, and purely by accident, he teaches the young Elvis Presley to dance, participates in civil rights history at the University of Alabama, gives John Lennon the lyrics to Imagine, and helps to trigger the scandal that was Watergate.
His impact on those he loves is much greater, but again, how much of it is deliberate, and how much is just a by-product of his character, is open to question. He only ever wants to be happy with the people he loves and respects, and who have been kind to him. And the results are extraordinary.
In a way, I quite envy him. As he says, "I'm not a smart man - but I know what love is." There are worse ways of going through life.
