The art teacher, Ms. Perrigrew, tells Doug: "I don't know what I like, but I do know what Art is." This joke lampoons the common phrase: "I don't know much about Art, but I know what I like."
Doug's imaginary Art show at the museum features paintings of his friends in the distinct styles of several famous artists, such as Van Gogh, Dali, Lichtenstein, Warhol, Picasso, and Chagall.
When Doug wonders if he was like the guy on TV, he appears as the American painter Bob Ross in terms of his look and the way he talked.
