Logic Puzzle - Raymond Smullyan

This quote was added by user71700
There is a question I could ask you that has a definite correct answer - either yes or no - but it is logically impossible for you to give the correct answer. You might know what the correct answer is, but you cannot give it. Anybody other than you might possibly be able to give the correct answer, but you cannot! Can you figure out what question I could have in mind?
