Strictly, analogies -- false?

A point can be made of the Griceian sort:

"That cigarette ain't healthy"

"Look, darling; it's animals which are healthy or fail to be so. So, I would grant you that a cigarette ain't healthy, but I guess I knew that."

---

This does not work.

Better scenario:

"That urine is healthy".

"It's not. Strictly, it is FALSE to say that that urine is healthy" (Sorry, the example belongs to St. (so-called) Thomas Aquinas, an Italian -- and a saint, so-called).

And so on.

In this way, analogy relates with metaphor and disimplicature. Or not.
