* Brick and Skipper in the backstory of TennesseeWilliams' play ''CatOnAHotTinRoof'' - that is, if you believe Brick when he vehemently denies they did "sodomy" together:
-->'''Brick''': Why can't exceptional friendship, ''real, real, deep, deep friendship!'' between two men be respected as something clean and decent without being thought of as--\\
'''Big Daddy''': It can, it is, for God's sake.\\
'''Brick''': -'''''Fairies'''''...
* ''Theatre/AYearWithFrogAndToad'': Frog and Toad were always good friends in the original kids' books, but TheMusical elevates them comfortably to life partners at the very least. They even invade each others dreams to sing about how much they like each other. Twice. ("That's funny, you've been in all my dreams too...")
* Estragon and Vladimir from ''WaitingForGodot''. They even have pet names for each other and put off killing themselves because of the slight possibility that one of them would live and be left alone. They were going to hang themselves so they could get ''erections.'' There is so much HoYay in this play, [[http://en.wikipedia.org/wiki/Waiting_for_Godot#Homoerotic_interpretations Wikipedia]] even has it's own entry on it.
* ''Theatre/AvenueQ'': Rod and Nicky, who are {{CaptainErsatz}}es of Bert and Ernie respectively. "We live together, as close as people can get / We've been the best of buddies ever since the day we met!" Which segues, just a song later, into "If you were gay / That'd be okay / I mean, 'cause hey / I like you anyway / Because you see / If it were me / I would feel free to say / That I was gay / [[HaveIMentionedIAmHeterosexualToday But I'm not gay.]]"
** Subverted, as [[spoiler: while Nicky fits the trope perfectly, Rod only qualifies for the "Life Partner" aspect. [[TransparentCloset Rod has non-platonic, repressed feelings for Nicky.]]]]
* [[spoiler:Voldemort]] and [[spoiler:Quirrell]] are ''at least'' this by the end of ''AVeryPotterMusical''. ''Senior Year'' takes it to the next level.
** Harry and Ron, though, firmly hit this trope in both musicals:
--->'''Ron''': Favorite way to say "red wines" in a German accent?
--->'''Both''': Red Vines!
--->'''Ron''': (hugging Harry) Oh my god, where have you been all my life?
--->'''Harry''': In a cupboard under some stairs!
* Prof. Henry Higgins and Colonel Pickering in ''Theatre/{{Pygmalion}}''/''MyFairLady''.
* [[UnreliableNarrator Mark]] [[StepfordSmiler Cohen]] and [[DefrostingIceQueen Roger]] [[IdolSinger Davis]] in {{RENT}}. Their duet, "What You Own" comes complete with ManlyTears and a big climatic ManHug. The blink-and-you'll-miss-it instrumental reprise of "I Should Tell You" during their fight in "Goodbye Love" is also heartwarming.
* Oscar and Felix in ''Theatre/TheOddCouple''.
* Mame and Vera in ''Auntie Mame''. The musical version gives them a duet about their relationship, "Bosom Buddies."
* Elphaba and G(a)linda from ''Theatre/{{Wicked}}''
* Kate and Queenie from ''Literature/TheWildParty'', although [[WithFriendsLikeThese they don't look it]]
* Janet van der Graaf and ''TheDrowsyChaperone''
* Buddy and Ben in ''Theatre/{{Follies}}''
* In the works of Creator/WilliamShakespeare:
** Rosencrantz and Guildenstern in ''Theatre/{{Hamlet}}''. Possibly Hamlet and Horatio.
** Antonio and Sebastian in ''Theatre/TwelfthNight''.
** Antonio and Bassonio in ''Theatre/TheMerchantOfVenice''.
** Rosalind and Celia in ''Theatre/AsYouLikeIt''. Even marriage doesn't likely break it up, since they marry brothers.
** Proteus and Valentine from ''Theatre/TwoGentlemenOfVerona'', and (more humorously) their respective servants, Launce and Speed.
** Mercutio and Benvolio, and/or Mercutio and Romeo, in ''Theatre/RomeoAndJuliet''.
** Lucentio and Tranio from ''Theatre/TheTamingOfTheShrew''. Tranio is "as secret and as dear" to Lucentio "as Anna to the Queen of Carthage was"[[note]]Refers to Queeen Dido and her sister from Virgil's ''Literature/{{Aeneid}}''[[/note]], and he'll do anything to help Lucentio.
* Rosencrantz and Guildenstern in Tom Stoppard's ''RosencrantzAndGuildensternAreDead'', if only because they're the main characters in that.
* Elder Price and Elder Cunningham at the end of ''Theatre/TheBookOfMormon''.
* Enjolras and Grantaire from ''Theatre/LesMiserables''. This is somewhat more evident in the musical than in the book, probably because of how it's usually staged.
** At least half the fandom can provide serious, significant, historical and textually-based evidence for their being canon-implied gay for each other (starting with the homsexuality coded via classical references to figures like Orestes and Pylades, heading into more explicitly canon territory with the book's acknowledging that Grantaire "loves" Enjolras, reaching a turning point when the two [[spoiler:die as equals, with more or less [[HoYay HoYay-tastic]] dialogue depending on the translation]], and then going off into fan-speculation based on interpretations of their motives throughout the text from there ...). It's the kind of thing you could write a serious academic paper, if not a thesis, on.
** This was all made worse by the fact that the two characters were played by real life best friends, Ramin Karimloo and Hadley Fraser, in the 25th Anniversary Concert.
*** When all the other students walk off with their girlfriends at the end of "Do You Hear The People Sing", these two leave with their arms around each other.
** Jason Forbach and Joseph Spieldenner, who play Enjolras and Grantaire, respectively, in the US 25th Anniversary production are engaged.
* "[[Literature/TheEmigrants Kristina from Duvemåla]]" has Robert and Arvid.
* Max Bialystock and Leo Bloom in ''TheProducers''. "'Til Him" is one of the most touching (and funny) love songs ever sung by one straight man to another.
