Adventure Time, Season 8

[Finn, Jake and Lady Rainicorn come across a giant humming sentient pit]

Finn:
It's a face hole! This is where the song's coming from. [the pit blows them away] Oh, nice pipes.

Hole:
[speaks] "Wait, can you hear me?"

Finn:
I've been hearing you like, all day. You're a lovely singer.

Hole:
[laughs] "Really? No one's ever said that. Shut up!"

Finn:
It's true!

Hole:
"Well, I've had a lot of practice. Thousand years, give or take."

Finn:
Say whaaaa?!!

Hole:
"Yeah. I've been here singing from the very beginning of Ooo. Since I can't move from this spot, singing is my only outlet. I can neither participate, enjoy nor prevent disaster. So I sing."

Jake:
Is this like one of those patterns that's supposed to have a 3D image in it, and everyone can see it except you?

Finn:
Well, why can't they hear you?

Hole:
"Only two kinds of people can hear my song—those who see the world with pure childlike wonder, and those with a deep sense of loss in their hearts. To everyone else, I'm just a period in a sentence in the book of Ooo."

Finn:
I don't know about child eyes, but I have been going through a rough patch. It sounds like you have, too.

Hole:
"Yeah, I guess so."
