That Pooh lad is wise beyond his years.

"Hell is other people" - Jean Paul Sartre.

Carl Sagan on The Pale Blue Dot
https://en.wikipedia.org/wiki/Pale_Blue_Dot

We succeeded in taking that picture, and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there – on a mote of dust, suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.
[...] To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known

Orson Welles improvised classic from The Third Man

After all it's not that awful. You know what the fellow said – in Italy, for thirty years under the Borgias, they had warfare, terror, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland, they had brotherly love, they had five hundred years of democracy and peace – and what did that produce? The cuckoo clock. So long Holly.

More of a dialogue I guess but from Trainspotting..

Tommy: Useless mother****er, that's what she called me. I told her, I'm sorry, but these things happen. Let's put it behind us.

Spud: That's fair enough.

Tommy: Yes, but then she finds out I've bought a ticket for Iggy Pop the same night.

Spud: Went ballistic?

Tommy: Big time. Absolutely ****ing radge. 'It's me or Iggy Pop, time to decide.'

Spud: So what's it going to be?

Tommy: Well, I've paid for the ticket.

Jellon Lamb: (singing) Oh, Danny boy, the flies, the flies are crawling

Too many favourites, so i'll give one by Ed from Youghal:

Brian Clough.."I wouldn't say I was the best manager in the business. But I was in the top one."

And also from Mohammed Ali about Brian Clough..

"There is some fella in London named some Brian -- Brian Clough. Some soccer player or something. I heard all the way in Indonesia that this fella talks too much. He says that there is another Muhammad Ali -- there is just one Muhammad Ali.

"I'm the talker. Now Clough, I've had enough, stop it."
