"You will hang me."
Since they cannot hang him - that will make him true and they can only hang him for a lie, and they cannot shoot him - they would mean he told the truth but if they shoot him it's a lie - he is free to go.
You are driving down the road in your car on a wild, stormy night, when you pass by a bus stop and you see three people waiting for the bus:
1. An old lady who looks as if she is about to die.
2. An old friend who once saved your life.
3. The perfect partner you have been dreaming about.
Knowing that there can only be one passenger in the car, who would you choose?
