Adventure Time, Season 2

Finn:
What do you think, Dr. Donut? Any clues?

Dr. Donut:
[touches Mr. Candycane's skull] Hmm... I think it was the guy would screamed, "I'm gonna kill you." [all passengers murmur indistinctly]

Colonel Candycorn:
Uh— no, no! I-it-it wasn't me, I swear!

Finn:
Passengers, passengers! I don't think it was Colonel Candycorn.

Colonel Candycorn:
Oh, well, well, thank you.

Finn:
No! In murder mysteries, it's never the first person you think of — never ever.

Marshmallow Kid:
So, who do you think it is?

Finn:
[turns to Colonel] Colonel, do you have any enemies on this train?

Colonel Candycorn:
Well, uh... well, just one. And his or her name is...

[the train enters another tunnel and fades to black; a skeleton of Colonel Candycorn is shown with many passengers screaming]

Finn:
See?! I knew it wasn't him! But now we need to figure out who his enemy is. It could be anybody.

Candy Person:
It could even be you.

Finn:
[beat] ..Yes, it could—except I didn't do it.

Candy Person:
But... we don't know that.

Finn:
[points at him] You singled me out to take suspicion off yourself. Are you Colonel Candycorn's enemy?

Candy Person:
What? No! I was just trying to join in on the conversation!

Finn:
Suspect numero uno!

[the train enters yet another tunnel with the Candy Person's skeleton shown upon exiting the tunnel. Finn gasps]

Finn:
Rat traps! I really thought I was on to something.
