Can someone explain Smiling Friends to me? I have a two housemates who won't stop talking about it every week and I watched a few episodes with them and I just don't get it.

They constantly reference animators or voice actors in the show and laugh at literally everything that happens and I just don't get it. I feel like there's a lot of background knowledge of the artists previous work that they all watched years ago that I just somehow missed it and want to know what exactly all of that is to just understand it.

I get that you can't like everything and humor is subjective but at the same time I don't hate it. I'm just neutral towards it and I want to understand it more. I've watched a lot of shows in the past that I didn't enjoy when I started watching them but as I powered through it I began to understand and enjoy it (even revisiting previous episodes of the show and finally *getting it*) so I'm just asking if anyone can point me in the direction of what makes this show funny.
