You are on an island with wizards who always lie, and knights who always tell the truth.
You meet one islander who offers you two cupcakes. One is poisoned and the other is safe to eat.
You ask him, Which cupcake is safe to eat?
To this he makes the following two statements:
If I were a wizard, I'd say the one on the right.
But I'd say the one on the left if I were a knight.
Which cupcake is safe to eat?
