Adventure Time, Season 7

Bubblegum:
You really like chopping wood, huh?

Peppermint Butler:
I'm not chopping wood. I made a toothpick from the ancient elm! See?

Bubblegum:
Oh-hoh! He-heh— [the tree crashes through the window] Whoa!! [a scathed Marceline peeks out the tree]

Marceline:
Uhh, knock knock.

Bubblegum:
What the dip, Marceline?!

Marceline:
Sorry, it was supposed to be a joke. Actually... I have something really serious to ask. I want you to do the procedure. The one we talked about?

Bubblegum:
I'm sorry, but I don't think you'd make a good blonde.

Marceline:
No, not that. I don't wanna be a vampire anymore.

Bubblegum:
[gasps] Oh, my globness!

Marceline:
You said you were working on a cure, right?

Bubblegum:
[sighs] Well, the machine is built and the serums are ready, but... are you sure you wanna do this?

Marceline:
I'm sure. Some bad things happened to me when I was little. When I became a vampire, I was just a messed-up kid. Now it's a thousand years later and I'm still messed up! [Peppermint Butler nods] I don't want to spend eternity like this... with this emptiness. I want to grow up.

Bubblegum:
Okay... let's do this.
