The Haunting of Unit 4B
Ghost Doug Does Doors
Our ghost fixed the door. Now he wants a raise.
Previously: Penny cracked the closet door chasing a creak, and logged a $60 deposit deduction.
When the closet door Penny broke is mysteriously repaired, the roommates decide their ghost is a free contractor named Doug, and Penny tries to sign him to a lease addendum, until Stan counteroffers on Doug's behalf.
From the script

IkePenny cracked this closet door in half. Now it's perfect. Not a scratch.

LunaA ghost repaired it overnight. That is a textbook manifestation!

PennyI don't care who. That's sixty dollars back in my deposit.

LunaAnd look! The ghost left his screwdriver on the floor.
Next time: what's cooking in the ceiling?
