Is there any better example of positive thinking than Monty Python’s Black knight??

Come on then.
What?
Have at you!
You are indeed brave, Sir knight, but the fight is mine.
Oh, had enough, eh?
Look, you stupid bastard, you’ve got no arms left.
Yes I have.
Look!
Just a flesh wound.
Look, stop that.
Chicken! Chicken!
Look, I’ll have your leg. Right!
Right, I’ll do you for that!
You’ll what?
Come ‘ere!
What are you going to do, bleed on me?
I’m invincible!
You’re a loony.
The Black Knight always triumphs! Have at you! Come on then.
All right; we’ll call it a draw.
