The "Mythbusters" are often proved wrong... Generally their methods lack any sort of scientific or engineering basis. It is an amusing show though.

Actually, they do work pretty hard to do the science, behind the scenes. Can you cite an example where they were wrong (and have not yet corrected themselves through a revisited show)?

Besides, steel teeth are pretty blatantly not going to work like Jaws' teeth did..

That's only because they are assuming that Jaws was a human. What if he had a titanium skull and hydraulic muscles?
