This is the 1,001st post at the NonSequitur.  I failed to note the 1,000th posting, the last one.  I was more excited about the post.  Regardless, Colin and John have done a great job with the blog, and I'm really pleased to have been brought in.  And in honor of the event of passing the 1000 post mark, I want to pose the question: can a joke work as a counter-example?  Here's a test-case.

Ludwig Wittgenstein was a philosopher, one that did his most influential later work in the aphoristic style.  Asking questions, putting things in a cute way, and so on.  He made many of his points, really, with lines that could pass for jokes. One of the core commitments of Wittgenstein's system was that to speak a language, you have to share a form of life with others who speak the same language. To illustrate this commitment, he has the enigmatic-oracular line:

If a lion could speak, we could not understand him (PI: p.223)

Again, the thought seems to be that since a lion doesn't share our form of life, its language would be inaccessible to us. 

Now, I'm not so sure about Wittgenstein's point, simply on the reason that if we're able to recognize that the lion is speaking a language, then we must be capable of having at least a decent grasp of what he's talking about.  That is, a necessary condition for attributing to X the capacity to speak a language is that you've some evidence that the sounds X is uttering are semantically contentful and also what those contents are.  (Or at least that you know that they are contentful and you could find out what those contents are.)

But I want to play Wittgenstein's game of making points instead of with straight argument, but with aphoristic style.  And so, here's my proposed counter-example (in the form of a joke):

So a lion walks into a bar…  He sidles up to the juke box and selects a Led Zepppelin song.  He then plays a round of darts.  Then he goes up to the bar, and he says to the bartender: "Wittgenstein wouldn't get this joke."

Should someone committed to Wittgenstein's philosophy of language be troubled by this joke?  Is it funny, regardless?  What are the consequences?
