Grim and Mandy in “Unfinished Business”

Grim

[after knocking on Santa's door and nobody answering] Strange, the door is locked and nobody is answering.

Mandy

If you saw the Grim Reaper at your door, would you answer?

Grim

Good point. But there should at least be some frightened screamin'. [reaches into pocket] Hang on, I got something for this.

Mandy

What?

Grim

[pulls out a key] A skeleton key!
