In the episode where Peter tries to suduce Luke Perry, notice the part when Meg gives the report called "corruption in city hall" to Brian ( the dog) and Peter. If you look on the arm chair on the couch they're sitting on, there is no T.V. Guide on the armchair. After Peter says something like" Meg needs something that will pull those kids away from the rockemsockem robots and 90210 etc etc" he looks on the armchair and looks at the T.V guide which has Luke Perry on it! It wasn't there before when meg came in, but it was after she left, is it invisible? And as a joke if you pause the screen when it shows the T.V guide, if you look in the black print , yellow background it says, if you can read this Family Guy is on the air! Pretty Noticeable
