Hypothetical Scenario

All hallways are tube tunnels that you must crawl through. Going upstairs is net climbing. Going downstairs is a spiral slide. The entire first floor is a continuous ball pit. The kitchen has McDonald's cooking equipment installed including deep fryers and a broken ice cream machine. McDonald's characters make random appearances in the house. Grimace stands in the corner and watches any bedroom "activities".

If you accept these renovations, your mortgage is paid off in full and you own the house.
