I won't go as easy on him as you. The rats have been dishonest and sneaky for 60 or 70 years now. If he has not figured it out by now, he never will. There is a very good reason the Pubbies are called the stupid party. Sorry to be so negative, but I have no confidence in them, whatsoever.
You would have thought that somebody would have clued him in by now. How old is he?
