In the episode "Cruising With Marie," Ray and Marie board a cruise ship and are greeted by the cruise director as he is walking down the hallway their room is located in. However, the layout makes no sense; Marie and Ray's room has a porthole, and the hallway is going perpindicular to the porthole as opposed to parallel, like cruise ships are built. Also, the door is on the left side of the room; in cruise ships, the door is directly across from the porthole wall. In this configuration, the cruise director would simply be walking off the edge of the ship.
