Found this rather funny commercial from MeTV advertising Perry Mason, Matlock, Diagnosis Murder by having Ben and Dr. Sloan "watch" their shows on TV. This was actually a real scene from the show, but they superimposed the images on the TV but they did a very good job of getting them centered.
And it's a 25" Sony Trinitron, I'm pretty sure.
Others probably might not, but I love this!
