Are there little moments in the animation where the scene is okay, but then an additional action that's quite unrealistic is tacked on that makes it truly awful?
Here's my example. I was watching Replaceable You tonight and when Mr. Burns tries to hug that lesbian, she crunches him into a little ball and throw him into a wall. Okay, that isn't awful, but it certainly isn't laugh-out-loud funny. But then why the fuck does he scuttle away like a fucking crab? What the hell was that?
I can't think of particular episodes, but I also hate when Homer for some reason eats stuff that isn't even edible. I think there's a couch gag where it happens, but that moment in Mr. Spitz Goes to Washington with the Fox advertisement crawling across the screen is one. Would have been a lot more bearable if he crushed it with his fist or flung it away. But who the hell eats something that annoys them?
Spider Pig swallowing Homer's cell phone in the movie is pretty goddamn pointless.
I'm sure some people have some pet peeves with the new opening, too. Like people have brought up Marge's car flinging Homer through the wall. After seeing it once it's not funny week to week, so they may as well just had him sprint into the doorway like always.
