Suppose I offer you one of 3 prizes: prize A, prize B or prize C. Prize A is the best of the three, prize B is ok-ish and prize C is just something fake that's not even a prize.
You are to make a statement; if the statement is true I'll give you prize A or B, if your statement is false you'll get prize C (which is sad).
Can you force me to give you the good prize, prize A?
