Things you've only recently discovered about the game

[DaSpecial1]

Backaches (oh the irony since I have one right now).  I've had a sim's pregnancy suspended for a while to age her baby with her neighbors second set of offspring.  I had tons of babies in game but never saw this before.  Anyhow lately she's rubbing her lower back a lot or having the "receive a backrub" want.

She's an active sim and doesn't lay down much & thus seems to suffer a lot of backaches because of it.  Her friends that are pregnant don't display this behavior, but then they sit or lay down more and she tends to stand alot.  It's really very realistic and makes me appreciate TS2 all the more.

That you can have a double wedding/wedding party.  It was fun to watch.  They all rode off together in the limo and then came back and partied till the next day.

Whether it's some sadorandom event, or a glitch, I've had random Sims gift my playable Sims with a cake. They could be chatting, dancing; or whatever totally random behavior, and suddenly the other Sim will just be holding a plate of cake and give it to my Sim. It's the oddest damned thing I ever saw.

...I've been seeing this happen since Nightlife came out.

"I like you! Have some cake!"

I've realized that Sims congratulate each other for absolutely no reason all the time with Free Will on. Or, mine do ...

It's amusing isn't it? Hunt around the picture threads, I have one where a brother is congratulating his sister on getting some, uh, action. That one had be laughing for a good long while.

Menna and Eros had a baby to gether using the insim machine, I have the breast feeding hack and they both can breast feed the baby

I recently discovered that mean sims(0-2 Nice points, I think) can cheat while playing darts or chess by clicking on the chess/dart board.

I usually don't play with sound on, but I had it on today, and discovered that when sims reach a high level in creativity and play the piano, sims who stops to listen will sometimes clap their hands and say something like "Jah, Wolfgang" (As in Wolfgang Mozart). I just thought this was a little funny

Also, it seems like Mortimer has a liking of UFO's (and they apparently like him). Some sims I have to keep looking in the telescope for days and days before they're abducted - even doing the "call on aliens" action.
Mortimer was abducted about five or so times just today... even during daytime (only thing I did, was making him call on aliens). He also kept rolling the want "get abducted" since I did it the first time.
But he also stood crying over the toilet for some strange reason (with a toilet thought bubble), so my suspicions about the guy being crazy still stands...

I discovered yesterday that you can use the small steps to make a standard size staircase  Was changing around a house I'd dl'd and couldn't get the staircase out of it. Finally remembered the sledgehammer and I think it changed the section/picture in the build window (like the eyedropper does.)

"OMG - they STRETCH???!!!!??!!!

So that was nice.

[Lerf]

And the modular staircases are much better to use in the house, since more than one Sim can go up or down them at a time, so Sims aren't constantly getting blocked from going upstairs.  I hardly ever use the regular staircases any more.

That if a sim dies while shopping they leave a shopping bag instead of an urn.

[kaoz666]

That's...uhm...actually kinda...disturbing...lol.

[luckynumber]

Yeeeeeah.... definitely. 

I recently discovered that when you use the telescope during the daylight hours, Mortimer Goth will come over and slap you silly. That made me laugh!

[Lerf]

Actually it depends on the neighborhood.  It seems to be the Sim with lowest "character number" who isn't an NPC who does the slapping.

I recently discovered that film and literature Sims will walk around reading a book when they're bored.

Yes it was, .  I fell asleep playing one of my popular business lots and several customers had "shopped" themselves to death. I didn't save but it was pretty funny in a sick sorta way.
