Inserting jokes is not that easy. A joke needs to be told in person, create laughs and get retold, go viral.
Similarly there's no reliable formula for viral videos etc.
And, the Russians were pissed enough and cynical enough and often drunk enough to get pleasure from creating their own. Laughing at the cruel unjust absurdity of their Situation was some of the last bit of power they had to form their narrative.
People in all countries make jokes about the problems of their society or lives, or their government or bureaucracy or businesses; you don't have to live in "cruel unjust" absurdity or be "drunk enough" to do so, or be afflicted by any other stereotype or trope.

That is correct, but as a Romanian some of the best jokes I've ever heard were created late under Ceausescu's regime, in the '80s, when the economic and political situation was the most dire. The most famous character was Bulă (https://en.wikipedia.org/wiki/Bul%C4%83), whose life ended just as Ceausescu fell. I haven't heard better jokes since then. One which I remember as a kid, told by my father to his drunken friends (back in the day your dad could actually take you over with him to the pub, even if you were only 7 or 8 years old):
"""
There's a ministerial inspection at the school where Bulă studies, and, as usual, he sits in the last bench (Bulă is not the brightest of pupils). As Bulă's hot lady teacher starts presenting the lesson one of the inspectors, who was sitting right next to Bulă, tells the other inspector, without most of those present hearing it, apart from Bulă:
'This teacher's legs really do look hot!'
As the lesson continues the lady teacher poses a question for her pupils to answer. Bulă, sensing his chance, frantically raises his hand. The teacher, slightly bewildered by Bulă's recently found excitement for learning, tells him:
'Tell us the answer to my question, Bulă, and good for you for showing interest in the lesson!'
to which Bulă answers:
'Your legs look really hot!'
Of course that makes the teacher very mad, she starts cursing at Bulă and throwing him some slaps. After all is said and done Bulă turns back and tells the two school inspectors:
'Well, you stupid lads, if you didn't know the answer to the teacher's question why did you whisper it?'
"drunk enough" because alcohol served to lower inhibitions. Westerners really don't know what it's like when speaking too freely could land you in trouble.
I learned Russian and German in college in the early '80s and knew a fair number of emigrants from the former Soviet bloc (Russians, Ukrainians, Poles, East Germans). They all shared this same sense of humor. Which served them well once they figured out they weren't going to become millionaires just because they made it to the U.S.
My parents always said that bad politics creates the best comedy. There's a lot of comedy shows filmed in socialist Poland and they're amazing. Both really clever and funny. Even though they had to be reviewed by censors first, the things that got through were still very much about politics. Some so pointed, I still don't know if the censors were too lazy to read the script, or ignored the rules...
I always wonder if the subversive elements that make it through aren't "missed" necessarily by a censor. I like to think that it's an act of subversion, a protest-by-omission, by some of the few people of conscience deep in the belly of the beast.
Speaking of "kinds of humour", it is British humour that is special. Russian jokes are very similar to German, both nations share quite similar attitude in jokes.
Isn't it obvious? All information can be used against you. So if the targeted entity knows what you're training your agents with to appear like natives citizens, you can change that context or create traps.
In other words, they were classified because they were in use by the CIA not due to being somehow special.
