When you spend a sufficient amount of time in a community, the inside jokes became more and more obtuse. A lot of jokes will be derivative of some derivative of a derivative of a joke. Logically explaining a joke will never be funny.

This happens with my wife all the time, I show her a meme and she doesn’t get it. When I start explaining it, it becomes clear you need to have seen the evolution of a number of bits of media to put together into this “3rd level derivative” joke.

So in conclusion, yeah this joke might never be funny for you. The link might give you a logical explanation to understand in the future. Just accept it’s an inside joke that’s not for you, and that’s ok.
