You haven't seen Arrested Development? Holy shit man, just lean close and let me tell you how it is. Yes, closer. That's fine. So. This is not an "American sitcom" in the way you seem to mean. When you say it like that, it sounds like you're talking about Married With Children or Everbody Loves Raymond. Get that ish out of your mind right now. This is nothing like an "American sitcom". There are no camera-facing couches with bald men grabbing their balls or jokes about how tall your brother is. This is fucking sublime humor that will have you rolling on the floor, clawing at your throat for air. You will have to pause the video and sit there and think for a few minutes just to be able parse the rapid-fire jokes that just flew through your ear canal and how they referenced references made two seasons ago that you'd never EVER be able to figure out unless you'd spent that last hour Googling "Arrested Development Easter Eggs and References" (don't do this btw). And even if you never knew about any of that stuff and, like most of us, just went in blind and hoped for the best, you'd still be so awestruck that from here until your death you can't HELP but think of everything you see in terms of Arrested Development references, and the next time you do something you think you shouldn't have done, Will Arnett's face will pop up in your mind and, a smirk quickly escaping from the corner of your mouth, you'll blank your face and mutter to yourself:
"I've made a huge mistake."
And then you'll rewatch the whole series for the fifth time.
