Ok so basically someone says something random and then you have to say what it goes in.
You stop until you reach something crazy like "Milky Way goes in the Universe" or something.
In reality, if you can't think of something after, you lose.
Example:
OP: What does a baby go in?
Player 2: A baby goes in their cradle.
Player 3: A cradle goes in their house.
Player 4: Their house goes in a city.
Some can be very tricky.
If the next player can't think of anything, say you are "stuck" and change the subject.
I'll start.
What does a sandwich go in?
