What if the statement that it’s a hoax is a hoax? That’s the most likely case the way things are going in Washington and the rest of the world today.
Or the statement that "the statement that its a hoax is a hoax" is itself a hoax??
As Charley Brown said, in a similar situation, "AARGH!!"
(As one old enough to have been around at the original time -- it is definitely a left-wing hoax, made up to attack the anti-communist right. It is really amusing to see some on the right now falling for it!)
