A Riddle

A Roscoe will be awarded to the first person with the answer.  (Riddle provided by Uncle John's Bathroom Reader Calendar)

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. What am I?

Have at it then.  It's been a while since I've given a Roscoe out to anyone.
