Answer:
I have thirteen hearts but no body or soul.
I can sizzle like bacon. I am made from an egg. I have plenty of backbone but lack a good leg. I peel layers like onions but still remain whole. I can be long like a flagpole yet fit in a hole.
I am partially baked. I am not completely lit. I am a portion of the moon. I am lesser than full wit. I am a divider of the hour. I am not a total lie. I am a sibling through one parent.
Six legs two heads two hands one long nose. Yet I use only four legs Wherever I go.
You throw me out when you use me and take me in when you are done.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
