It would be exactly as funny and exactly as interesting, which is to say: not very.
This is right up there with noticing that sometimes the "b" in certain English words is completely silent! Haha isn't that totally irrational and crazy you guys??
Well, there are some languages that semi-regularly update their orthographies to better match their pronunciations.
And yes, the grammarians arbitrarily inserting random silent letter into middle of the words so those look more regular or match the (supposed) etymologies are annoying. English "doubt" never historically had "b" inside it either written or spoken: it was "dout", and it was pronounced like this. Same happened to French "doigt" — it used to be "doit" for as long as language itself was called French, but then some Latin-loving guy decided to stick "g" in so that it would be more obvious that the word descended from Latin "digitus".
I didn't find it particularly funny either. It's mostly predicated on this belief that somehow we "should" have optimized our date and time system and that it's silly that we're using an inconsistent, legacy system formed for many cultural reasons.
My analogy is that it's like writing a tweetstorm about how aliens landed on Earth to find that humans use different languages! And different writing systems! How quaint!
How I would have ended would be with the aliens saying we should just adopt galactic standard time because it is so much easier, but in fact it is twice as complicated and confusing, but they are used to it so it appears simple. Still funny better message.
