corn on the cob
A house with two occupants, sometimes one, rarely three. Break the walls, eat the boarders, then throw away me. What am I?
When you prepare me for dinner you take off my outside and cook my inside.When you eat me, you eat my outside and throw away my inside. Who am I?
I can be good for you, I can be bad, I can be found all over inside and outside your body. I am microscopic, single-celled and have no nucleus.
