Lyrics:

Bart:
Dad, I'm really glad you're still alive

Homer:
Yeah, it's every parent's dream to outlive their children. Good night, son
(Homer turns off the light, closes the door, but then Sideshow Bob appears.)

Sideshow Bob:
Hello, Bart
(Bart screams and then searches for the buzzer.)

Sideshow Bob:
Looking for this? (holds the buzzer in his hand) Now I'm going to take some advice that was given to me by Lenny, and kill you without doing. One thrust and the deed is done. I....I can't do it

Bart:
Huh? Why not?

Sideshow Bob:
Well, I guess I've—dear God—grown accustomed to your face!
I've grown accustomed to his face
And dreams of gouging out his eyes
I've grown accustomed to my hate
My plans to lacerate
To disembowel
To hear him howl
The very reason that I live
Is plotting how to watch him die

Homer:
(banging on the door) Bart! Turn down that original cast recording and go to sleep!

Sideshow Bob:
I know this chubby scalawag
Has made my life a living hell
Surely, if I drank his blood
I'd be at peace...
But well...

Bart:
You've grown accustomed to my face?

Sideshow Bob:
This isn't a duet

Bart:
Sorry

Sideshow Bob:
I've grown accustomed to your fear
Accustomed to revenge
Accustomed to your face
