"Butch Cassidy and the Sundance Kid" (1969) tells the tale of two bank robbers who try to go straight and just can't pull it off. Paul Newman and Robert Redford play the lead roles, as Katharine Ross co-stars.
I'm 26, and I'm single, and a school teacher, and that's the bottom of the pit. And the only excitement I've known is here with me now. I'll go with you, and I won't whine, and I'll sew you socks, and I'll stitch you when you're wounded, and I'll do anything you ask of me except one thing. I won't watch you die. I'll miss that scene if you don't mind.
