SMG4 has discovered the best meme yet (he thinks), in which you can see a fish spinning with videogame music in the background. It made him laugh so much that he wanted to share it with his friends, until he got a text from his FISH friend Fishy Boopkins, explaining that his aunt died.
You and the rest of the SMG4 Crew are there, to make company to Boopkins and JubJub into these painful and tragic memories. Boopkins shares some words of melancholy and appreciation towards his dead aunt, but SMG4 can't help but get distracted when he realizes that he is in front of... A DEAD FISH. It takes a lot of his willpower not to laugh or think about memes, specifically the meme of the dead fish spinning, but when Boopkins starts to cry and everyone, even Mario and Bob, looks down in a moment of silence and respect, SMG4 can't hold back anymore and makes a commentary that makes everyone stare at him with ugly gazes.
"WHAT THE DED' FISH DOIN'??"
He... he just memed in a funeral.
