PSA Knight: That Cobb is unaltered and is in vg-ex+condition.
King Arthur: What?
PSA Knight: After a further review PSA determines that it is unaltered and in vg-ex+ condition!
King Arthur: I have no quarrel with you, good Sir Knight. But that card has been worked over by a card doctor.
PSA Knight: Then you shall die.
King Arthur: I command you, pursuant to PSA's guarantee, to admit that PSA made a mistake!
PSA Knight: PSA admits fault for no man.
King Arthur: So be it!
[they fight until Arthur cuts off Black Knight's left and right arms]
King Arthur: Victory is mine! PSA is wrong!
[kneels to pray]
King Arthur: We thank thee, Lord, that in thy mercy -
[cut off by the Knight kicking him]
PSA Knight: Come on, then.
King Arthur: What?
PSA Knight: Have at you!
King Arthur: You are indeed brave, Sir Knight, but the fight is mine!
PSA Knight: Oh, had enough, eh?
King Arthur: Look, you stupid bastard. Someone rebuilt the corners and fixed flaws in the card!
PSA Knight: 'Tis but a shadow on the holder!
King Arthur: A shadow? It used to be an SGC 30. The card is altered!
PSA Knight: No, it isn't.
King Arthur: What about these before and after photos?
PSA Knight: [after a pause] I've not made a mistake.
King Arthur: You liar!
PSA Knight: I'm a PSA grader! I'm infallible!
King Arthur: You're a loony.
