Lew Brookman making a sales pitch that captivates Death himself in "One For The Angels", saving a girl's life in the process.
"The Jeopardy Room". A Soviet defector is being toyed with by 2 spies in his room. He must find a bomb in 3 hours (it's in the phone which will explode if he picks it up after it rings). He takes his chances and escapes. The spies enter the room. The phone rings and one of the spies answers it. The defector was on the other line and he is on his way to London.
Romney Wordsworth's death from "The Obsolete Man". Turning the tables against a totalitarian state on live television, all on its own terms.
Wordsworth got to pick his own method of execution, and he chose a bomb exploding in a room. This leads to added awesomeness because he traps the chancellor that helped condemn him in the room with a half-hour to go. Wordsworth faces death with dignity, but his foe doesn't. In the last few moments, just as Wordsworth expected, the chancellor cracks and pleads to be released. A pleased Wordsworth agrees and the chancellor escapes the room just in time. Problem is, since the execution was televised, everyone witnessed the chancellor's weakness and the state deems him obsolete - something Wordsworth almost assuredly knew would happen. The ending implies he is given the much more painful death of being torn apart by a furious mob.
Jeff Myrtlebank beating up Orgram and later scaring off the townspeople in "The Last Rites of Jeff Myrtlebank".
In "He's Alive", an elderly Holocaust survivor finds that his young roommate has become a Neo-Nazi and is giving a speech to some impressionable youngsters. The old man declares, "Never again!" and punches the teen out. Later, the teen angrily shoots him, but the old man decides to Face Death with Dignity and warns the Nazi that, "You can't kill an idea with a bullet."
Colonel Sloan's speech to the colonists at the end of "On Thursday We Leave For Home". The leader of the colonists, Captain Benteen, formerly kept the colonists together with the idea that a ship would come to take them back to Earth, because the world they had found was practically uninhabitable, but when the rescue arrives, he's less than willing to give up his authority. He tries to convince them that Earth is a terrible place, and death is certain for all of them if they go. This is how Colonel Sloan responds:
Sloan: Captain Benteen! Why don't you let your children vote on it?!
Benteen: Only if they know what's waiting for them! Only if they know the Earth is not a garden. It never was a garden! And it never will be a garden!
Sloan: Fair enough! Fair enough. Then I'll tell you what Earth is. It's a race of men, struggling for survival. Just as you have survived. And Captain Benteen is quite right when he tells you it isn't a place of all beauty. We may yet have wars, and there still remains prejudice, and I suppose as long as men walk, there will be angry men, jealous men, unforgiving men. But it has one thing that you don't have! One thing. It lets every man be his own master. There won't be any Captain Benteens down there for you. There won't be anybody to tell you when to eat and when to sleep and when to meet. There won't be anyone to tell you when to dance or when to sing or how to play. And instead of the thirst, you may feel hunger! Instead of heat, you may feel cold! But you'll be men and women, you won't be sheep! You won't be a kindergarten! And when you pray to God, his name won't be Benteen!
From the revival episode "I of Newton", two words: "Get lost." Which is how the protagonist gets rid of a demon who wants his soul.
More specifically, there was a challenge presented: if the protagonist could come up with a task or question the demon couldn't complete, his soul remains untouched; a bonus was being able to ask him 3 questions of anything involving himself. After botching the first, the protagonist uses the remaining two to uncover the following: the demon had literally no limitation on what he could do, where he could go and if he could get back. In other words, he could not get lost.
