Yeah but in this case it seems a number so out of reality that from my point of view it is funny (but I can't laugh about it, here in Brazil people think that the ex-president Lula is the hidden owner of the biggest meat company of the world).

It's out of reality from your point of view. What makes it starkly un-funny is the fact that for the true audience for that statement, it's not out of reality at all.

That comment was so far off base it was probably intentionally designed to be wrong, but other statistical anomalies aren't lies. Your typically tedious rebuttal won't work for any of those.
