A question I've been wanting to ask for quite a while: has anybody ever understood any of the jokes Sims keep telling to each other?

I haven't but I'm sure the jokes aren't meant to be deciphered, like their chats are not really understandable either.

Not the jokes the sims keep telling each other, no. But I've found the penguin to be a proper jokester, if you interpret its talk bubbles while chatting with the snowman (it loves talking about hot soup, fried eggs, and gets really excited about skiing (Potentially a Super Mario thing, with the penguin level...?)

The jokes they tell each other are absolutely hilarious to other Sims, but we players are too stupid to get them. At least that's what Andrew told me.

There's one dirty joke though, and I'm sure you'll know which one I mean, if you've seen it, that I'm sure is about an absolutely gorgeously sexy girl -- or boy!

I distinctly remember a joke in Simlish that, while impossible to understand the words, followed the meter of a limerick perfectly (though the fact that I remember dialogue means it's probably from TS1 not TS2, come to think of it...)
