This is
the introduction to every episode of The Simpsons. I am using this, which is the first version I found, as my reference; the details of the plot differ from episode to episode.
We begin with
☁️☁️☁️☁️ (a cloudy sky, on which the name of the show appears).
Then
⚛️/OOOOO🔥/🍩/🖼️ (we see the Springfield nuclear power plant, then a tyre fire (thanks to Stiv for pointing that bit out in comments) and then what I think is the town hall -- where one of the other sequences needs to be inserted; see below. Then the local donut shop, and then a big billboard).
We continue on to
🏫⬛✍️✍️✍️😂🔔🛹⬅️↘️🍂🥴↗️👨🦰 (we see the elementary school and look through a window to a classroom where Bart is writing lines; the bell rings and he runs out, to be seen a moment later leaving the school on his skateboard; he jumps into a pile of fallen leaves, causing some consternation)
and then cut to
👨🦲🥒↗️↙️⬅️2→3🙎♂️🙎🏾♂️⏬ (Homer with a lump of green radioactive material that I suppose does kinda resemble a cucumber; a "N days without an accident" sign has N changed from 2 to 3; the people making the change fall off their ladder)
at which point
🏪🔵🛍️👶💲🛒/👶👀👶:😠 (Homer leaves -- this isn't shown in the emoji -- and then the scene changes to a supermarket where Marge is at the checkout; perhaps the blue circle represents her hair; Maggie is on the conveyor belt, and after being scanned and deposited in Marge's trolley she has a staring match with another baby)
and then again we have an abrupt change of scene to
🎶🎶🎶🎶🌞🎷🎶⬅️🎷 (the school wind band where Lisa is playing her saxophone exuberantly, is sent out and leaves still playing)
and yet another to
🚗👨🦲⏏️🥒🍴🛹😂➡️🙋♂️🤷♀️ 8👶🏾🙍🏾♂️ 🙂🙂🙂🙂🙂👮♂️👀🛹➡️ (Homer is driving his car, throws his radioactive fuel rod or whatever it is out of the window where it is eaten by someone sitting on a bench; Bart skateboards past, and encounters lots of people including a policeman)
and yet another to
🚘👶↩️👶↪️🔵🔊👶🔊 (Maggie appears to be driving Marge's car; Marge -- yup, that blue circle is definitely her hair -- is actually driving and honks the horn)
at which point
👨🦲⬅️🚗/🚲🌞🎷/🛹😂/🚘😱🏃♂️ (Homer's car pulls up to the Simpsons' garage, Bart's skateboard bounces off its roof, Bart is nearly knocked over by Lisa's bicycle -- either those last two bits are the wrong way around or the order varies between episodes -- and then Homer walks in front of Marge's car and ends up being carried on its front into the garage and flung into the house)
and
🛋️👨🦲🔵👶🌞😂❕ (we see the whole family converging on the couch in their living room, usually with some peculiar and amusing twist; in the "reference" intro linked above, this "couch gag" goes on rather longer than usual)
after which
📺 they all end up watching the television, and the episode begins.
My list so far hasn't included
🦹♂️🦹♂️🗡️🗿⬇️👦
because
it refers to something that (at least in the version of the intro I've linked to above) comes in the middle of one of the other sequences, and which I had mentally filed as "must be a thing that's different every time" and therefore didn't think of trying to match with this, but as Stiv kindly points out in comments it's a permanent fixture in the Simpsons intro these days. It comes between the tyre fire and the donut shop in the second item: two miscreants saw the head off a statue and it falls onto someone else.
The title
is "The Simpsons", and it shows up at the end of the first "part".
The main characters are
👨🦲 (Homer) 🔵 (Marge) 👶 (Maggie) 🌞 (Lisa) and 😂 (Bart).
Credit where due:
I missed the tyre fire and failed to identify the falling-head sequence; thanks to Stiv for pointing those out in comments.
