Just for the record, this statement is demonstrably false. Often repeated, but false nevertheless.
If my wife and I are standing before you, and you ask if my wife is pregnant, and I say "No" while my wife simultaneously says "yes", one of us HAS to be wrong. It could be that my wife hasn't told me yet, or i wanted to keep the pregnancy private, but only one of the answers would be "true".
There can be only "one truth", not "many truths".
This is not true, but I doubt the OP meant it like this. (And you probably knew that). But the Law of Noncontradiction is so true that in trying to disprove it, you prove it.
