This is a sort of sequal to I'm WHAT? I hope it's at least funny.

The Ending
John is dead.
Karkat is insane.
All because of a little joke.
Well, he had it coming, always pulling those pranks.
But, Karkat didn't have to act so harsh.
Now, John'll NEVER have kids!
It makes you want to cry.
He'll never have those Derp-faced children writing novels in his life.
He'll never marry anyone.
On the bright side, he doesn't have to choose between Vriska and Rose.
But Vriska's fat. And Rose has a bad temper.
Yeah, John would stay single anyway.
But he can't.
Because Karkat killed him.
Now Karkat will never be seen as a sane person.
He'll be considered crazier than Gamzee on a rampage.
He'll be more forever alone than Equius and Eridan combined.
And Terezi is just laughing her butt off.
