Nice question.One niggle: asking people to assume that a schema is valid when a table doesn't have a primary key may encourage a very bad habit if some of your audience don't know any better. Maybe "pretend" would have been a better choice of word than "assume".
Tom, I think it was referring to the schema "Playground", which the table was created in.
