Does that count? It's not a TV show in the show, but it is pretty much a second show embedded within the main one.
It's great how they mix episodic and serialized shit together like that, too. You got the wacky alien one-offs, and then you have a large story unfolding within the tiny world of the shrunken people that live inside Yumulak's wall.
Some time ago there was a website where you could stream a whole collection of shows-within-other-shows. Like, you could have Itchy and Scratchy listed, just like in a streaming platform. I think it was called NESTflix.
First that comes to mind is Itchy and Scratchy (The Simpsons)
Trying to torrent that
McBane from the Simpsons. Someone edited all the small clips together and they make a coherent 80s action movie parody.
I prefer “Terence & Philip” as my South Park Show within a show.
I’d argue “Sanctuary Moon” is a more enjoyable show than Murderbot.
And who can forget that show with the “I’d buy that for a dollar!” tagline? Evidently I can, because I can’t remember what it’s called.
On that last one, all I can think of is RoboCop.
the scary door from Futurama
Also Hypnotoad
All glory to the hypno toad!
“Ow My Balls!” from Idiocracy.
You were both made to laugh and at the same time be the point of the joke for laughing.
Climbing for Dollars from The Running Man.
I'd legit watch All My Circuits from Futurama.
And I'd probably shamewatch whatever Mojo put out in the marvel universe.
The Rise and Fall of Sanctuary Moon.
Ghostfacers was fun.
The Wall in Solar Opposites.

That's funny the first thing that came to mind, albeit not necessarily my all time favourite, was SilverCops
The Adventures of Captain Proton from Star Trek Voyager
I'll also list these, not because they're my favorites but just because they haven't been mentioned yet:
Los Dias y Los Noches de Monsigñor Martinez from King of the Hill.
McBain from The Simpsons
Various interdimensional cable shows from Rick and Morty

Wormhole extreme from SG-1
Idk if it's my favorite but I remember the Justice Friends from Dexter's Lab. https://dexterslab.fandom.com/wiki/Justice_Friends
The viking dude from that is a large part of the reason I thought guitar was cool as a young kid.
MILF Island
from
30 Rock
We No Longer Want To Hit That
MILF Island on 30 Rock, along with their many other fake shows, is right up there with Tropic Thunder's fake movies.
The snack zone!
From
Jet Lag: the Game. Available on Youtube and Nebula.
The snack zoneeeee! 🎷🎷🎷
Psycho Dad, no question.
Perry the Platypus
Prescription Passion from House had more than they put on the show and was enjoyably ridiculous.
Honorable mention to Psycho Mom!
Who's the gal who needs no man?
Killed him dead with the frying pan
Did it 'cause he missed the can!
Psycho Mom
Psycho Mom
Psycho Mom!
Jolly good
