The Hot Rod - S9-E12
Continuity mistake: While Miss Mamie is trapped, when Ike and Miss Emily find the special wall panel to control the door, the hidden door opens and the top of the door is plain with no molding, but when Ike leads the Baldwin sisters into the room, in the shot from within the room there is molding across the top of that door.
