History TearJerker / MenInBlack

* When introducing MIB to J, K says there was "one kid who got lost in the wrong back alley". Later on, we find out that K was that kid and that he left his former girlfriend to join the agency. The script makes it clear that unlike later recruits like J, K had no choice in the matter. He was forced to join just for being in the wrong place at the wrong time.

--> '''K:''' I've just been down the gullet of an interstellar cockroach, kid. That's one of a hundred memories that I ''don't want''.
* Before that, K wistfully says of the stars in the sky, "They really are beautiful, aren't they?" - obviously pining for a day that the stars were just that, stars and nothing more.

--> '''K:''' See you around, kid.
--> '''J:''' No. ''(braces himself and readies the neuralyzer)'' You '''won't'''.

--> '''J:''' You know what they say. Better to have loved and lost then never to have loved at all.
--> '''K:''' Try it.

--> '''J:''' No. ''(braces himself and readies the neuralyzer)'' you '''won't'''.

* Orion the Cat in the first film. Before his owner was murdered, he really seemed to love and spoil him.

--> '''K:''' Son, I've just been down the gullet of an interstellar cockroach, kid. That's one of a hundred memories I ''don't want''.

!!Film:

---> '''K:''' Son, I've just been down the gullet of an interstellar cockroach, kid. That's one of a hundred memories I ''don't want''.

!!Animated series:
* The end of "The Neuralyzer Syndrome," where the neuralyzed K is "renewing his vows" by [[spoiler: saying one last goodbye to his father]].
* The end of "The Inanimate Syndrome" when Agent Aileen leaves.
--> '''J:''' Fuel fumes really sting the eyes, huh?
--> '''K:''' ...yeah.
* The beginning of "The "J" is for James Syndrome" starts off with Jay accidentally going for a joyride in the LTD and getting neuralyzed by the MIB. The worst of it is the fact that as they do it he starts screaming in protest while some agents hold him to keep him from getting away.
* The end of "The Endgame Syndrome Part, 2", where all the people of Earth learn the truth of aliens and don't freak-out in a mass panic. Only for the MIB agents to neuralize the whole planet because they don't like the idea of losing their jobs. Talk about shallow.

!!Films:

* The second movie states that K's wife left him, of course this was so K could be in the movie, however in-universe it's rather depressing when you think about it. Being an MIB kept him from the woman he loved and even with his memory erased he still was unable be with her because deep down he was still an MIB man at heart, no matter what life K chooses to lead there's a void he can't fill. Or, rather, his decades long absence changed the both of them, and she'd moved on emotionally.
--> '''K:''' Son, I've just been down the gullet of an interstellar cockroach, kid. That's one of a hundred memories I ''don't want''.
** Before that, K wistfully says of the stars in the sky, "They really are beautiful, aren't they?" - obviously pining for a day that the stars were just that, stars and nothing more.
** Taking it further is the realization from the third film that one of those memories K doesn't want [[spoiler:is the memory of neuralizing J to forget what happened to J's father.]]
*** As well as [[spoiler:J's father dying after pushing K out of the way]].
* There's also the "Light of Zarthra" flashback from the sequel.
-->'''K:''' This is wrong. It was night, and it was raining...
* "It rains because you're sad."
** Boy, was he right.
* Griffin's backstory, especially because he's such a hopeful, kindhearted person. This is a guy who lost everything, yet still came to love Earth as his home anyway. His sadness at having failed to stop Boris before is only matched by his hope that the current situation won't end the same way.
--> "I lost my planet. I don't want you to lose yours. It'll take a miracle, [[CrowningMomentOfHeartwarming but if you pull this off it'll be my new favorite moment in human history.]]"
* The twist at the end of the third film, that [[spoiler: J's father was killed by Boris, and the young J never knew what happened because K neuralized him to spare him the truth. This is all witnessed by Future!J.]]
** "Would you like to take a walk with me, James?"
** "Where there's death, there will always be death."
** A retroactive one because of this [[spoiler: Hey, K, have you ever flashy-thinged me?]]
* Boris killing his girlfriend. This was just so heartless. Thankfully, she is saved by Boris dying in 1969.
** One feels far less sorry for her when one considers she was willing to break a mass murdering killer out of jail.
** It's not clear that she's even his girlfriend. She could just be some girl with a bad case of hero worship or an in-film case of DracoInLeatherPants.
* Part this, part NightmareFuel. When J time skips he is hit in the face by a newspaper on the stock markets crashing, and as he's falling other men in suits are jumping out with him [[DrivenToSuicide to their deaths.]] Ouch man. Ouch.
