I know that joke too.
Still not a paradox-merely an untruth.
Yes, in the real world it’s a picture of a pipe. But the message is also inside the picture, and in that universe the object in question really is a pipe.
But not a penis.
I suppose the appropriate audio clip would be Elton’s:
If I asked your neighbor here what your answer would be, what would he say?
Whatever he says, do the opposite.
I was going to tell you about paralipsis, but changed my mind.
Allow me to clarify:
[QUOTE=Lewis Carroll]
“You are sad.” the Knight said in an anxious tone: “let me sing you a song to comfort you.”
“Is it very long?” Alice asked, for she had heard a good deal of poetry that day.
“It’s long.” said the Knight, “but it’s very, very beautiful. Everybody that hears me sing it - either it brings tears to their eyes, or else -”
“Or else what?” said Alice, for the Knight had made a sudden pause.
“Or else it doesn’t, you know. The name of the song is called ‘Haddocks’ Eyes.'”
“Oh, that’s the name of the song, is it?” Alice said, trying to feel interested.
“No, you don’t understand,” the Knight said, looking a little vexed. “That’s what the name is called. The name really is ‘The Aged, Aged Man.’”
“Then I ought to have said ‘That’s what the song is called’?” Alice corrected herself.
“No you oughtn’t: that’s another thing. The song is called ‘Ways and Means’ but that’s only what it’s called, you know!”
“Well, what is the song then?” said Alice, who was by this time completely bewildered.
“I was coming to that,” the Knight said. “The song really is ‘A-sitting On a Gate’: and the tune’s my own invention.”

Performatives.
Thanks - I knew it was something like that, but you know when you just have a mental block on some piece of information for some reason?
In that case, I think the term the OP was looking for is performative contradiction, whose meaning is fairly obvious, but I can’t find a really good online cite.
