What I said last night, after my Sims honeymooned in the Far East was, "It's still the best game ever, I don't care what anyone says."
(I seem to say that a lot!)

Why do you insist on trying to play kickybag in the kitchen? You know there's no room there!

WTF. Why are you bringing a book outside to read to the toddler where there's dropped rubbish and roaches? I told you to take her inside, so you put her down and go inside without her ...

"Oh sh*t, not Morty!" *Tries to get Bella to plead for his life* "What do you MEAN 'no actions available'??"
"Nervous! Stop. Stuffing. Your. Face."
"Tara, stop hitting on Goopy. You're married! One of you will meet Fredrick the cowplant if you don't quit."
"Who comes in a nightclub to jump rope? Malcolm, have him leave."

As I save a household, I look at the clock and see there's not time to play an entire day, but more time than I need just to shut the game down, shower, and go to bed. "I'll just take a little peek at the next one..."

An oldie but goodie: "Get. In. The. Goddamned. ENERGIZER!" (For maximum effect, read aloud through clenched teeth.)

Said after a Sim with all motives in or near red kept getting out of the energizer to complain about his motives, pee on himself, and fall asleep in the pee puddle rather than stay in the Energizer for the three seconds it would have taken to solve everything.

While my sim finishes making Ambrosia;

"Hello, what have we here? A dinner display going on, hmm? How marvelous, I'll go get the rest of the family an- aaand he just it on fire... happy now?" ಠ_ಠ

"Don't put the baby on the floor!"

Ambrosia? Sounds like you need the Sims 3 discussion board over here: http://www.modthesims.info/fd.php?f=561 this is for Sims 2.

Things I've said recently: "Argh, get out of bed now!" I have Apartment Life so couples do the Apartment Life morning cuddle after they wake up, but they are very slow in untangling from each other to get out of bed. It annoys me when they take their sweet time and almost miss the carpool or the baby needs to be changed and they take forever to untangle and get out of bed to change the baby's diaper.

It wasn't Ambrosia, I keep on forgetting the name of the desert in sims 2 that they light on fire etc. Why do I assume it's Ambrosia? I really don't know, just forgetful.

*stares at computer* No. You did not! Dude, your lover died of a disease two seconds ago! Don't flirt with his friend! I don't care if second dude is your lover too! Have some class!

Two seconds later:
You jerk. At least wait until the grim reaper leaves before making out with him!

"I'm so completely done with you people."
-almost every single time i play
"NO STOP WHAT WHERE ARE YOU TAKING HER COME BACK YOU EVIL PERSON WHAT WHERE DID THE PARENTS GO DKDKJDKD"
When my couple that had twins held a wedding party, got married, and went on their honeymoon leaving the twins completely unattended. Leonard (from the Big Bang theory) decided to take one of the babies. I eventually got her back but I was screaming at Leonard the whole time
"There's no time for that you have to go to work!"
"WHY ARE YOU MAKING YOUR BED THERE'S A ROBBER CALL THE COPS YOU IDIOT STOP"
When my sim just had to make her bed before even considering to call the cops.
"How do you fit a hot tub in that bag is that a portable black hole"
Same robbery
"You could've stolen the litter box"
Same robbery when there was a dirty litter box that I moved to the middle of nowhere because I had no space in the house
"WHY ARE YOU TAKING A SPONGEBATH "

I know Baked Alaska is a dessert that they can make that requires them to light it on fire, I can't think of any others right now. Ambrosia is a Sims 3 food that is used to resurrect a ghost Sim.

"Why are you getting out of bed in the middle of the nite? *Sim proceeds to make the bed* "What is Grimmie doing here? NOOO!" Elder sim just had to make that bed before taking a trip - suitcase in hand . .
*Sims gets up - makes the bed* "What about the other side? It's a double bed, 2 sides, make up both of them!!" Sims that make their bed every day as child/teen seem not to realize when they grow up and get married, the double bed has 2 sides.
"Why are you taking out trash? You just moved in, there is no trash!" I don't use compactors or trash bins anymore, they constantly take out trash that shouldn't exist. Saves a lot of wasted time that can be utilized doing something more important.
"You're on a date! Get back here!"
"Why am I sending you to do that? It's in your wants list . . if you don't want to do it, don't add to wants!!!"
"NO COPS AND ROBBERS IN THE HOUSE!" I AM GOING TO FIND A MOD TO STOP YOUUUU!!!" Annoying game, loud, they get in other sims way and it's an outdoor thing and it can't be canceled.
"I wish the pointer had a finger that can thump you on your empty head!"

"WHY ARE YOU SINGING KARAOKE IT BLOCKS THE STAIRWAY THAT SOMEBODY NEEDS TO USE OR ELSE THEY'LL STARVE!!!!!"
Me when one of my sims was about to starve because someone was singing karaoke and the karaoke machine was blocking the stairway that led to the kitchen. In the end I moved the fridge upstairs and made my sim have some cookies.

"WHY THE HECK IS THE POLICE HERE?! WHAT DID I DO? ALL I DID WAS ADOPT A PET!"
When I figured out that the police comes when you call on the phone to adopt a pet.

"WHY IS THE COUCH RIPPED TO 3 PIECES OF WOOD?!!!"
When the couch got ripped apart by my a Siamese cat that my sim owned.

"THERE IS NO TIME TO COOK THAT HOT DOG ON THE GRILL BECAUSE YOU'RE GONNA BE LATE FOR WORK!"
When my sim was cooking a hot dog on the grill and the carpool for work had already left but I didn't want a fire to start.

"SPECIAL EVENTS CAMERA I THOUGHT THAT I TURNED YOU OFF!!! I DON'T CARE ABOUT THEM WOO-HOOING. I DO IT ALLLLLL THE TIME WITH COUPLES AND I DON'T CARE WHAT THE HECK THAT THEY DO. SO SPECIAL EVENTS CAMERA, YOU CAN SHUT YOUR FACE."

Lately I've been yelling this constantly -

"OH, DON'T YOU DARE HAVE QUADRUPLETS. DON'T YOU DARE. IF YOU HAVE QUADRUPLETS I WILL KILL Y-- ....crap, you had quadruplets."

You don't have to allow the multiple option even if you have the mod installed, you know.

Just now I invited household on the family that includes the newly-raised teen who had previously burned to death. She picked out another visitor - another teen girl, the granddaughter of the hostess - and started harassing her. Every time I saw her I was saying: "Don't make me wish I hadn't resurrected you!"

You want ANOTHER baby? You don't have room or money for another bed. OK fine, but this time you'll have QUADS! Course I know that won't stop the little rabbits from wanting MOAR babies!

Eat, sleep, pee, bath. How about if there is no toilet and you have to survive on pizza, ya lazy good for nothing.... Actually that sounds interesting.

1) "WHY ARE YOU DOING THIS? I DONT CARE IF DINA CALIENTE IS ON THE VERGE OF DYING, YOUR JOB IS MORE IMPORTANT THAN YOUR GIRLFRIEND!"

2) "Oh no. It's a girl."

3) "AGH I DONT WANT TO TALK TO YOU. OR YOU. OR YOU. IM LEAVING THIS PLACE. BYE TOWNIES!"

"What's Mortimer doing her-"
"LEAVE MY SELF SIM ALONE YOU CRADLE ROBBING FREAK!"

"Shit!" - I muttered this when my computer crashed before I was able to save the game.

Making them survive on pizza will just make you jealous as they can eat as much pizza as they like and it won't make them fat.

mine is "why you check him out you just got married"
"why on earth you want to eat again, leave that fridge alone"
"don't go anywhere! I'm paying you to stand here and serve customers"(my employer leaves cash register unattended when I give him order to stay there)

I don't care about your moonbeam voodoo shit! Go away!

I said that at the Gypsy woman one time.

"Can you not."
