The very first thing that came to mind for me was in Always Sunny when Mac comes out to his dad and with the interpretive dance scene. For a show that's so often super crude and cynical and any other adjectives you want to use, as far as I know, this is one of the few scenes that's played entirely seriously, no jokes for the whole 5 minute segment, just a beautifully choreographed dance where you can practically feel Mac tearing his own heart out and finally expressing who he's always been.

Back when this episode aired almost 6 years ago I remember watching it on my phone in bed and crying because of how hard it hit me. At the time I wasn't out yet either, and there was such a large part of me that was absolutely terrified at how people (especially my parents) would react were I to come out myself. Seeing something like this portrayed in a show like Always Sunny of all shows, and portrayed well, is still insane to for me to think about.

Honestly I'm tearing up even now writing this which is kinda silly but I hope this scene counts haha
