Where did that number come from?

> Also 99.99% chance the guy was making a joke.

If you have no idea who this person is how can you even begin to make such an assumption? You are in fact 100% wrong.

Not getting jokes is a skill issue, what can I say.

You can say you are wrong because you don't know the person at all.

I will say I have very low confidence that your perception of reality and actual reality match.
