The night following the day Eric Cartman finds out he's dead, he pays a visit. Spoilers for the Death of Eric Cartman.
Note: I do not own South Park or any of its characters. Based off the Death of Eric Cartman. Oh, and I know that the God of the Jews is Jehovah/Adonai/Lord/I Am, but I doubt Cartman would know that.
"Wooo! Wooo!" Cartman moaned, as he made his way up the drain pipe to Kyle's room; one good thing about being dead was that he didn't have to worry about keeping quiet. No one would hear him anyway. Sliding the window open, he slipped into Kyle's room. "Kahl! Psst! Kahl!" He poked the sleeping boy on the shoulder. "Kahl!"
Kyle groaned and rolled over. "Wha…?" He muttered, his eyes blinking open.
Cartman burst into tears as his rival seemingly met his eyes. If only Kyle could actually see him. "Kahl, I kn-know you can't h-hear or s-see me, but I-I need to s-say this and maybe whoever the g-god of the Jews is will pass on the m-message someday." Kyle opened his mouth, no doubt in shock, wondering what had poked him; poor Kyle; probably thought his house was haunted. "I-I know I wa-wa-wasn't always nice to you bu-but I always con-considered you a friend. I n-never meant it all those times I ripped on you for being J-j-jewish! I just ne-never knew how to be a fr-r-riend! My mom never tau-taught me tha-that it wasn't okay to ma-make fun of people and now it's too late! But I just wanted you to know, that if I had to choose between killing Kenneh or Stan or killing you, I'd totally kill Stan because then, you and I, w-we could be like be-bestest friends an-and take over the world and you could be second-in-command. I-I-I just wa-wanted to know how much you meant to me. Goo-goodbye, Kahl. Wooo! Wooo! Wooo!" Cartman burst out into a fresh round of tears and rushed from the room, down the stairs, and out the front door.
Startled Kyle just lay in bed for a moment, then went out into the hallway, looking down the stairs. A second later, his parents' door opened. "Kyle!" His mother cried. "Are you all right? We thought we heard the front door slam!"
"I'm fine, Mom." Kyle sighed. "That was just Cartman being weird."
"Oh…well, goodnight, then."
"Goodnight." Kyle said and then went back to sleep.
