Here is a short riddle that depends on taking an everyday word out of its usual setting: What has a door but no room?
Answer: A car.
A car can have two, four, or even more doors, but those doors do not lead into rooms in the way the doors of a house do. They lead into the passenger compartment. That makes a car a straightforward answer to the riddle.
The question works because most people immediately connect a door with a house, apartment, or other building. Once you stop assuming the door must belong to a building, the answer becomes much easier to spot.
