Costas reminds me of when we were in school. Every now and then a teacher would wind up with a classroom full of idiots he or she couldn't do anything with. They can't fail everyone, so they grade on a Bell Curve. Then, the lesser idiot gets a B+. That doesn't mean they're an above average student. It just means they're an above average idiot. The grey matter in their skull is still dormant. Costas was that student.
