I got a good laugh from the next part: > Satan, pretending to be offended by your skepticism, asks "Whose signature do you trust? Just say the name, and I will have them sign my class. Would you like Microsoft to sign it? There's a guy over there who owes me a favor." You come to the conclusion that a signature cannot by itself transform a suspect class into a fully trusted class, so you decide that you need a more credible security mechanism.
