I recently saw a feature (20/20 or 60 minutes or some other similar show) on chicken McNuggets (as well as other nuggets). The ingredient "chicken" actually is a combination of meat by-products derived from chickens at some point. Ever wonder what they do with the skin and bones they get from the boneless skinless chicken breasts that are sold at the store? Yup, that's right. The bones are ground into a bone meal paste; the chicken skin (which contains most the fat on the bird) is also turned into a pasty type slop. Then both of these are mixed together with about 10% actual meat, pressed in to a form, frozen and shipped. When at a fast food place order chicken fingers that have an identifiable meat texture and muscle "grain" (just like wood). If you get something that is a consistent texture of particle board or pressed sawdust you are eating bone and skin, the stuff even scavengers leave behind.

Bon Appetite!
