"The Song of Purple Summer", as all cast members dead and alive assemble on stage to sing a song of hope, love and the world going on.
Especially unbelievably heartwarming after Moritz and Wendla's ghosts will Melchior to live on after their deaths, and stop him from committing suicide.
Melchior and Moritz's hug when Moritz sneaks into the Principal's office and finds out that he has passed the midterm exams. The two hug at the end of the scene, but the two actors must remain hugging in the background (not lit) as Fraulein Knuppeldick and Herr Knockenbruch talk about these goings on in the foreground, which makes it rather funny yet must be unbelievably awkward for the actors.
The line before they hug which Moritz says in his joy is "Truly, heaven must feel like this!", which John Gallagher Jr (who originally played Moritz) incorporated as the last line of his speech when accepting the Tony Award for Best Performance by a Featured Actor in a Musical.
The part of the hayloft scene when Wendla realizes that she wants to go through with what they are about to do, and manages to kiss Melchior back.
Wendla: Melchi, no—it's just—it's...
Melchior: What? Sinful?
Wendla: No. I don't know!
Melchior: Then why? Because it's good? Because it makes us FEEL something?
Wendla: (Exasperated) I don't know! (Wendla returns his kiss fully)
"Touch Me" is an Intercourse with You song that manages to be heartwarming at the same time, because it's so emotional and gorgeous compared to other similar songs.
The ending of the Deaf West revival had Moritz and Wendla waiting for their friends, presumably in heaven. And when Melchior enters, Wendla takes his hand and they walk away.
At one point in the revival, when Hanschen (played by Joey Haro) says "The middle-terms, that is," Moritz had to hold Ernst back because the latter wanted to physically fight/confront Hanschen and defend Moritz.
At the end of Totally Fucked in the 2015 revival, the cast starts clapping and cheering for Melchior as he flips off his teachers. Wendla is standing closest to him and claps with the most excitement and admiration. Especially heartwarming because Sandra Mae Frank played it with maximum adorableness.
The entire premise of Deaf West's productions of the musical, providing deaf Broadway lovers a chance to continue loving the shows they watch and be able to understand what's going on. Broadway truly can be for everyone.
Perhaps only for blocking and logistic reasons, but Hanschen lifting Anna from her wheelchair and carrying her into heaven.
Also, speaking of Hanschen in the Deaf West revival: after the abortion scene, he is the first to rush out and glare at a weeping Frau Bergmann accusingly.
On January 23, 2016, the day before the show was due to close, Broadway was shut down because of the blizzard hitting the East Coast of the US. The cast members, already at the theatre, decided to go out and give an impromptu mini-performance a cappella to the audience members who came. You can watch Totally Fucked and My Junk. Austin McKenzie's ears were firetruck-red since he was the only one who didn't have a hat or hood.
