Novel Sentence?

A fun game I used to play, before I married someone who found my fun games to be very annoying was, "Is This A Novel Sentence, Or Not?" I have a friend, we'll call him The Doctor, who insists that it is irresponsible to claim a sentence you say or wrote is novel, and has never before been produced in the history of time. He is, literally, a math genius, and believes that statistically speaking, the probabilty is always present that any sentence you create has been created before. If you try to make up a sentence, he will provide you with a context for that sentence.

Now, anyone who took Linguistics 101 will know that one of the defining features of language as opposed to any other form of communication is that a single language utterance/gesture/production (i.e. a sentence) can be infinite in length. Also, the possible language utterances/gestures/productions (i.e. sentences) one do are also infinte. Therefore, there are infinity sentences that have never been said.

Even so, The Doctor says we have no way of knowing which oddball sentences have been said/written before, and which ones have not.

I offer the follwoing sentence: "The only difference between a lampshade and the space shuttle is Max Headroom." This is a properly construced English sentence (though quite awkward) and therefore, according to The Doctor, I cannot claim it is novel. He believes the probability that someone else has produced it is just too high.

And on to my main point: I just got off the phone with a friend of mine. We'll call him Zandypants. During the course of our conversation, Zandypants said, "Yeah, fuck my art shanty." The context of this sentence is not relevant. Trust me, it made sense in context.

But this was a historic statement in that I am pretty sure it is a novel sentence. How can anyone have possibly said this before?

I could argue that Zandypants' desire to have his art shanty, er, fucked, is novel and therefore backs up my claim that because there are infinity unsaid sentences, and we can say with confidence that no one else has uttered such a request. I mean seriously, an "art shanty?" Wanting one's own art shanty to have sexual relations? Give me a break; that is a novel sentence. How about a little dose of common sense, The Doctor?

But this claim alone could support The Doctor's argument that there is a context for every single possible sentence, given that this one occured. So it is therefore impossible to claim that any sentence is novel. I don't agree, but I do appreciate the logic.

Who is right?
