Logic Joke

Dana Scott just told this joke, which he heard from Ray Smullyan:

Two professors at a math conference stand in front of a blackboard, on which is written the sentence “Only an idiot would believe a sentence like this!” The first professor asks the second, “Do you believe that?” The second answers, “Of course not! Only an idiot would believe a sentence like this!”
