*A letter and a CD is found on the floor.

S!Sans: What's this? (picks up both items)

S!Sans: Guys! C'mere!

*All the Sans come to Science!Sans.

S!Sans: It's for us.

US!Sans: <excited> Really?! Read it! (jumps up and down)

S!Sans: (clears throat)

Dear (every) Sans,
I know you're all bored to death, so I decided to let you guys have a little fun for a while. I attached this note with a CD you guys should watch. Trust me, it'll be fun. Also, once you start watching, THERE'S NO TURNING BACK. Okay, toodles!

UF!Sans: ...okay...

S!Sans: This is probably the CD that this person meant. (holds up said CD)

S!Sans: Question is, who sent this?

All Sans: (shrugs)

US!Sans: C'mon! We shouldn't delay! LET'S WATCH IT!

OT!Sans: I'LL GRAB THE POPCORN! (dashes to the kitchen)

US!Sans: (grabs CD from S!Sans) C'mon, magnificent people! Let us watch this movie! ...what is this movie?

*All the Sans gather on the couch in front of the Plasma Screen TV.

*Sans sits on the middle of the couch.

*AfterTale!Sans sits beside Sans Classic. (on the left side)

*UnderSwap!Sans sits to the right of Sans Classic.

*ReaperTale!Sans sits on the floor to the left of the couch.

*Gaster!Sans sits on the left armrest. (BECAUSE HE CAN LOLLLLL) (I didn't mean anything in that though.)

*All the other Sans not mentioned sit on the floor.

S!Sans: Alright, everyone, prepared?

All the Sans: Yep!

Gaster!Sans: ...I hope this isn't one of those stupid childish movies.

UF!Sans: I probably wouldn't last a second of this dumb movie. (rolls his eyes)

S!Sans: (puts in the CD then sits back to watch)

*"Silent Hill" plays.

UF!Sans: ...wait. I think I know this movie...

RT!Sans: I DEFINITELY DO! (puts a blindfold on US!Sans)

*A scary scene is shown.

*The author does not know which scene to put in.

UF!Sans: NO DON'T GO IN PLES

G!Sans: (widening eyes in fear)

OT!Sans: AAAAAAAAHHHHHHHHHHH

Sans: (snoring)

*A jump scare appears on screen.

*The author hasn't watched "Silent Hill" in a long time and has no plans of rewatching it.

All the Sans Except for Classic and UnderSwap: AAAAAAAAAAAAAAAHHHHHHH

US!Sans: Hey, uhhh, is Gaster!Sans screaming...?

Gaster!Sans: (screaming with the others)

US!Sans: Oh. Uh...

*After the movie...

I!Sans: (enters the house) Hey, guys, I-

All the Sans Except for UnderSwap and Classic: (still screaming)

I!Sans: Um...

*You still hear their screams.

I!Sans: Guys...?

I!Sans: ...okay. (goes to kitchen to find something to eat/drink)

*The screams continue even though the movie just ended.

Gaster!Sans: Is it over...? (opens one eye)

Gaster!Sans: Oh, atleast it's over. (regains composture)

Gaster!Sans: C'mon. It's over.

Every Other Sans: Huh? (regains composture)

UF!Sans: <very confused> Bruh. Why am I hugging you?

S!Sans: (shrugs)

US!Sans: (unties his blindfold) Oh, finally. I was getting tired of that.

US!Sans: Hey, guys! So, what went down? Was it cool?

RT!Sans: If you consider death hilarious, then okay. (still crying)

US!Sans: Hey, are you crying?

RT!Sans: No, I just have something in my eye! (laughs nervously) Hehe...

S!Sans: ...who wants to throw the CD into Hell?

All the Sans Who Watched: (raises hand)

S!Sans: Then who wants to touch the CD?

All the Sans Who Watched: (keeps quiet)

S!Sans: Alright, then. We're keeping it in there.

OT!Sans: I don't think I can sleep tonight... (sniffling)

*The next day...

G!Sans: (staring outside while holding a mug of black coffee)

UF!Sans: Hey, what are you lookin' at, man? (looks to Gaster!Sans's direction)

*The only thing you see is the dense fog...

*...and a triangular silhouette?

G!Sans: (staring intently at the silhouette)

UF!Sans: What is that...?

*The fog clears...

*You see the triangular pyramid man from "Silent Hill".

UF!Sans:AAAAAAAAAAAAAHHHHHHHHHHHHHHHH

G!Sans: (takes a picture of it) IS SILENT HILL REAL?! OH S*** WE'RE F***ING DEAD OHHHHHHHH F*** NOOOOO

...

...this was actually pretty long. Wow.
