The TV says a lot of things in The Wall, and most of them probably have some kind of meaning to Roger that we're not aware of. Speaking of which, during the Wall Live, the TV on Nobody Home says "Roger? Is he your doctor too? What a coincidence!" I thought that was funny, especially since it's the last time we see the TV before Roger dresses up as the Doctor in Comfortably Numb.
