You go to an island trying to find gold. Every inhabitant is either a knight or a liar. You meet two inhabitants, A and B.
A:Either B is a knight or there is gold on this island.
B:Either A is a liar or there is gold on this island.
What are A and B, and is there gold on the island?

There is never any gold.
A and B need say nothing about each other, because it's 'either...or'.
So Liar A says there is gold, and liar B says there is gold; result - there is no gold.
