If you already feel kind of weird lusting after the dad from The Waltons, then we've got some bad news: before Ralph Waite became an actor, he worked briefly as a Presbyterian minister. But this holy roller eventually decided that he preferred the stage to the pulpit, and he started a decades-long career that included a turn as slaver Slater on Roots (1979) as well as his iconic role as John Walton, Sr. But if it's Ralph's rear you're looking for, look no farther than Cool Hand Luke (1967), where he bares his creamy white seat meat under the watchful eye of a prison guard. Good night, John-boy!
