I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

What demands an answer, but asks no questions

What has many keys but can’t open a single lock?

What has to be broken before you can use it?

I can sizzle like bacon,
I am made with 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.
