Lady Gaga certainly has shock value, doing thing like wearing a dress made of meat and looking to have a hat filled with live cockroaches. As one of today's mainstream musicians pushing the envelope, it only seems appropriate to get a nod from one of the original envelope pushers, right?

Classic rocker Alice Cooper, one of the original musicians to use shock value during performances, gave a little nod to Gaga at a recent concert. Cooper, famous for songs like "School's Out for the Summer", performed a rendition of Lady Gaga's "Born This Way" to wrap up a show. Put this in the "we never saw this coming" file, and check out the video below.
