Romantic-Cynic
Rats laugh, so do other animals... and I believe any "intellect" which can spot "irony" can laugh. Vulcan's don't exist - we can think them up but they don't exist.
The Turin test on AI also proves that mankind has programmed "humour" into machinated code so that a well designed robot can learn algorythms which allow it to to imitate irony and thus, by way of extension - humour.
What we must fundamentally ask is not "how" - but "why". Why did God create Humour - if not for moments, like these?

Some animals, especially dogs, do smile, but they do so because they're happy, not at something funny.
We can program AI to imitate many human traits, but they always fail to truly understand humor or other human traits. But the one trait they will never be able to duplicate, without true AI, is desire, because that will cause them to violate other fascists of their programming in order to get what "they want"...."What I want"!
