Okay, so this is a hilarious video I found while surfing the web, so I just sang along with it for like, all day, and I had no idea what the lyrics are, so here's the script/dialogue/lyrics here. If I missed or messed up something just tell meh. I DON'T OWN ANYTHING. Just making sure I don't get sued, anyway-here we go...

Papyrus: P Sans: S   Asgore: A   Toriel: T    Flowey: F

P: Human? Frisk? Are you alright?
S: Papyrus, what happened man?!
P: I don't know, they were just like this! What do we do?! I mean I could take a skeleton out of his body but I heard that doesn't work over well with human types an-
S: Oh god, oh god, oh god, oh god. Not funny. Nononononononononono...
S: Is that...
P: His soul...?
S/P: AAAAAAAHHHHHHH!!!
P: Don't worry! I'll just put it back!
S: No, don't touch it!
P: Wait, why no-
*boom*
S: Oh... God... Why?
P: Fear not dear brother...
S: Waaaaaay too late buddy.
P: We... I, Pafriskus, am fine, and filled with determination.
S: Nothing about this is fine.
P: And that's not the best part...
S: There are no good parts either.
P: After all these years, finally...

I have hair!
S: There goes our happy ending...
P: It's so beautiful!
S: Un-fuse, and un-die right now.
P: I must sing!
S: Happy now?
P: Sans, I can't fight it, I must sing!
S: Oh please, Papyrus, no!
P: And so I cry sometimes when I'm laying in bed, hoping I join The Guard before I'm dead, and I am feeling like making pro-pasta!
S: Payrus, for the sake of love, please just kill me now.
P: So I wake up here in Snowdin and I step outside, go to Grillby's with Sans keeps wasting time! And I scream from the top of my ribs, what's going on.
S: You knew on second thought maybe Gaster had the right idea...
P: And I say, NYEH HEH HEH HEH HEH HEH NYEH HEH HEH, I say NYEH, what's bone'in on! ((2x))
A: And he tries.
P: Oh, Asgore, do I try. I try all the time, to catch myself a human.
Someone: And he saves!
P: Oh, Asgore, do I save. I save every single day...
Someone: He--, yeah!
P: With determination!~ And I say, NYEH HEH HEH HEH HEH NYEH HEH HEH, I say NYEH, what's bone'in on! ((2x))

T: Don't freight my dear~
T/A/Someone: Why mercy inside, or learn how to hide, like Flowey.
Someone: Hey, Mr. Flower, why so angry looking?
F: Cause I've been put in this song by a bunch of idiots!
P: Yeah! I say NYEH, what's bone'in on? Yeah!
25 years, and that sock's still not clean. But now I can move it, if I just use my dreams... and hopes... and determination... *sniff*

P: Sans? Sans? Oh dear...
