Code Golf Asked by Lebster on October 27, 2021
The goal of this challenge is to print the following tongue twister:
She sells seashells by the seashore,
The shells she sells are seashells, I'm sure.
So if she sells seashells on the seashore,
Then I'm sure she sells seashore shells.
This is more complicated than just calling your language’s print equivalent. Since there are a lot of repeated words and phrases, you can greatly decrease the size of your code by using other tactics.
Rules:
This is code-golf, so the shortest code wins!
Good luck!

As long as I didn't mess anything up, this should be the shortest possible without () and printing in loops.

Better than Bubblegum!
Husk's string compression is pretty good for this task, a straightforward compressed string would be 82 bytes long. Here, we apply just a single substitution to make it shorter. The compressed string we use here is
he sells seashpSpells by the seashore,
The shells she sells are seashells, I'm sure.
So if spells on the seashore,
Then I'm sure spore shells.
The structure of the code is:
ΓJx'p¨...
¨... The compressed string
x'p split on occurrences of the character 'p'
ΓJ and joined by interleaving the first substring between the rest
What this does in practice is replacing the character 'p' with "he sells seash" everywhere in the rest of the string. This substitution was the one that generated the shortest compressed string among the ones I've tried; multiple substitutions are possible but they didn't seem worth the longer payload. The letter 'p' was chosen because it generates words like "spell" and "spore" in the text that can be compressed very well by Husk.

Trivial algorithm, but nobody’s done it yet. I’m working on a better answer in a different language, but I don’t know if it should be posted in another answer or in this one. Shortening advice accepted, but I’m perfectly fine with just hard-coding it for now.

Unpacked:
`...`'!/|J
`...` - compressed string "She sells..." with '!' where newlines should be
'! - a '!' character
/ - split the compressed string at '!' characters
|J - join with newline characters
Maybe making a manual compression using the words will be shorter?

S230 by41h012 ‡e30,d.
So if1230 4˜123Že1h0.Decompress into the string literal:
S230 by41h012 are30,d.
So if1230 on4nd123ore1h0.
Then we do replacements with:
d
d` I'm1¨e` // "d" with " I'm1ure"
4` e3Že,nT”` // "4" with " the3ore,nThe"
3`1Á` // "3" with "1eash"
2`”10` // "2" with "he10"
1" s" // "1" with " s"
0`e¥s // "0" with "ells"

string a=" she sells ",b="shells",c="seashore",d=a+"sea"+b;Write(@$"She{d[4..]} by the {c},
The {b}{a}are sea{b}, I'm sure.
So if{d} on the {c},
Then I'm sure{a}{c} {b}.")
The @ allows for line breaks inside string literals.

Try it online! Explanation: In Retina, a substitution only makes sense if it's long enough l for the number n of repetitions. The substitution saves n(l-1) bytes in the compressed text but costs l+3 bytes in the replacement stages. This gives the minimum length required to be useful as follows:
Edit: As @Arnauld pointed out, you can count repetitions from the substitution entries as well. This means that although there were only 5 repetitions of space+s in my previous encoded text, there are also 3 repetitions in the substitutions, thus allowing me to save 3 bytes overall. (@Arnauld himself had only spotted 2 of the 3 repetitions.)
