Answer:
What goes through a door but never goes in and never comes out?
I can be cracked, made, told, and played. What am I?
I carry you down a gentle stream.
I fly when I'm on and float coming off.
I am a house with two occupants sometimes one rarely three. Break the walls eat the boarders then throw away me.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
