I love his delivery of this line, from Paint Your Wagon:
As a matter of fact, Pardner, you're right. But I ain't yet sunk to horse stealin'. Oh, I've salted claims, yeah. And I've sold whiskey to Injuns. And once a man in Walla Walla come at me with a gun and I killed him. I can't think of one commandment I ain't shattered regular. I never did fancy my mother and father, let alone respect 'em or honor 'em. And I have coveted my neighbor's wife - whenever I had a neighbor and he had a wife, mm, mmm! And I gamble and I cheat at cards, but there's one thing I do not do. I ain't never gulled a pardner. The one sacred thing, even to low scuff like me, is a man's pardner.
