This is difficult! A few in contention for me that aren’t already mentioned:

American Idol, Season 7 finale (David vs David)

Survivor, “If It Smells Like A Rat, Give It Cheese”

Arrested Development, “Pier Pressure”

Project Runway, “Innovation” (only cuz I can’t remember the ep with Santino’s Tim Gunn impression) 

I feel like it's said to death, but Breaking Bad's "Ozymandias" is pretty hard to beat. Just stunning all the way through. 

That said, I would also like to submit It's Always Sunny's "Charlie Work" for consideration. 

Euphoria "Stand Still Like the Hummingbird" episode was INSANE to me. Full on chills for the entire episode 

The season finale of Justified was absolutely perfect. 

The finale of The Good Place was one of the best 30 mins of tv i've ever seen! 

I’m sure there’s a Friday Night Lights episode in there somewhere.

I watched the penultimate episode of "This Is Us" last night, and it was... perfect. Beautifully shot, beautifully written, wonderfully acted. Just... perfect. I was a puddle of tears from 5 minutes in until the very last frame. What is a television episode that you would make ZERO changes to? (The pilot of "Desperate Housewives" and the bomb episode of "Grey's Anatomy" also fall in line of flawless TV for me)

What is a perfect episode of television?
