Two main things: grills and the bubble blower.
I love the aesthetic of the bubble blower, and it'd be great if everyone didnt just randomly cancel their action to go stare at the stupid thing. Gah! I had it in the main room of my sims house once, and all 8 of my sims like to go either applaud it or be horrified by it. To say I'd make a mistake would be an understatement.
The grills, oh man. Oh MAN. What is it with those things? Everyone will abandon -everything- to go grill themselves something that they're not even going to eat. Vampires doing so annoys me so much more, too—like, dude, you don't eat. You -can't- eat, (if they have withered stomach). You are burning, you fools. Get inside. Leave. the grill. alone!
