i can sizzle like bacon, i am made with an egg. i have plenty of backbone, but not one leg. i peel layers like onions, but still i remain whole. i can be long like a flag pole, but fit in a hole.
I am in books, but not in papyrus; I am in money but not in dimes; I am in octopuses but not in fish; I am in ballpoint pens, but not in pencils. What am I?
