(Sans)
It's a beautiful day outside.
Birds are singing, flowers are blooming...
On days like these, kids like you...
Should be burning in [bad word] 

Turn around kid, it'd be a crime,
If I had to go back on the promise that I made for you,
so don't step over that line,
Or else, friend, you're gonna have a bad time

(Chara) But guys like you are always just fools
 [bad word] at me, try to kill me with your fancy tools
(Both) Let's go, let the room get chiller...
(Chara) Let's go just another killer.

(Sans) Go ahead and try to hit me if you're able,
(Chara) But inside you know the end can't be evaded
(Sans) I can tell you're getting really sick of trying,
(Chara) But I [bad word] back after dying

(Chara) Why not let me win? You can't dodge forever!
(Chara) Even if the pain is more fun together
(Sans) I know you just reset each time I beat ya',
(Sans) But I'll always be right back here to meet ya'

(Chara / Sans) (I know you're made / I am made) of LOVE, LOVE...

(Both) This is where it stops, This is where it ends
(Chara) You keep telling me those words and hope that I would understand
(Chara) But even if I hear you I won't give up my attack
(Sans) Do you just like the feeling of your sins crawling on your back?

(Chara) Go ahead, kill me again I see you're able
(Sans) You should know by now that mercy's off the table
(Chara) You think I might decide to stop if you stay patient
(Chara) But i getting you with my determination!

(Sans / Chara) I know you made my friends all disappear / You know I made your friends all disappear
(Sans) But everything they cared about is why I'm here
(Sans) I am their mercy, I am their vengeance, I am DETERMINATION

(Chara) 
I'm entirely made of
LOVE
And i'm sure i'm stronger than you
LOVE

(Sans) I know you're made
(Both) Of LOVE
(Sans) But i think i'm stronger than you
(Both) LOVE
(Chara) I am stronger than you

(Chara)
OH

Here we are again...
Just me and [bad word]  right?
With your blasters your flashing eye?
You should better be prepared because soon...
Your last hour strikes!

Lyrics:
(Sans)
So let's go, let the room get chiller
Let's go dirty brother killer...
