[Original]
So a pyromaniac, a horse,  and a ninja all walked into a room.

On the other side of said room,  was their friends.

Out of the blue,  the horse's frenemy breaks down the door and screams,  "WE HAVE A FUCKING PROBLEM. " And then bites himself.

After he bit himself,  everyone was crushed.

The end.

[My version]

So Natsu, Jean,  and Pain all walked into a room,  talking about their own universes.

On the other side of said room,  was their friends; Marco, Lucy,  and Deidera,  who were talking about random things.

Out of the blue, Jean's frenemy Eren Jaeger breaks down the door and screams,  "WE HAVE A FUCKING PROBLEM, " and then bit himself. "Eren no-!"

After Eren bit himself, he transformed and everyone was crushed by his Titan form.

The end,  goodnight,  have a great life.
