Just noticed that there's a one-frame scene in the Breaking Bad episode S05E07, after Jesse watching Skyler walked away in her car-washing warehouse. Just like the stuff in the movie "Fight Club". Is there anyone taken a screen shot of that scene?
I've just checked and that's exactly where it fades to black for an advert break. It's clear you've seen a flash of an advert that wasn't edited out properly, and thought it was deliberate.
