"Explaining a joke is like dissecting a frog. You understand it better but the frog dies in the process." -- Elwyn Brooks White
But every joke has an emotional gravity and the longer you compliment it with other emotions (e.g. intellectual explanations), eventually escape velocity is reached and you're in an entirely different emotional state.
Airplane! has three laughs per minute on average (https://www.forbes.com/sites/andrewbender/2012/09/21/top-10-...). That's not much time pull in other emotional states. And that's on purpose.
Post -> Comment on Post -> Analysis of Comment -> Analysis of Analysis -> Analysis of the act of Analysis -> Question truth itself.
It's like that Wikipedia phenomenon where all articles lead to philosophy.
To the people saying the explanation ruined the joke, I’d ask you to take a minute to consider whether you viewed it as a joke or a shibboleth.
If only those who know ‘got it’ and explaining it ‘killed it’, then isn’t it by definition a shibboleth?
In-group language is exclusionary by definition. Is this a good thing?
