“Nothing could be further from the truth.”

In addition to becoming a hackneyed cliche (a phrase which itself is a “hackneyed cliche”), this sentence doesn’t parse, at least to me. What does it mean?

Does it mean that it’s possible for nothing to be further from the truth than for something to be? It reminds me of the old proof that a ham sandwich is better than eternal bliss.

Premise 1: Nothing is better than eternal bliss.
Premise 2: A ham sandwich is better than nothing.
Therefore: A ham sandwich is better than eternal bliss. QED

I hereby declare unconditional war on this cliche.

“Make no mistake about it…”

That last one actually does makes sense, but I also want to stomp it out anyway because it’s so overused, especially in Washington.

I’m figuring that if we can fully eradicate both phrases, most politicians will be struck dumb(er).
