The Deathvale Junction radio advertisement from the end of episode 11.

Lyrics:

Come on down to Deathvale Junction
When your pet no longer functions 
We can ease your pet compunction 
Come on down to Deathvale Junction
That's right

Ooooooo
Deathvale Junction
Deathvale Junction
Deathvale Junction
Deathvale Junction
Yeah

I apologize for the singing.
