Favorite Scooby Doo Conventions

My boss started randomly listing things that always happen in Scooby Doo episodes today, and he requested I make a list about it. Happy Friday.
  1. 1.
    The villain is almost always the only other person in the episode who isn't a main or recurring character.
  2. 2.
    Running in and out of rooms while the camera remains stationary, pointed down the hallway.
  3. 3.
    Linear chase scenes, where the entire gang runs past multiple objects over and over again to represent distance. #lamp #window #door #fireplace #repeat
  4. 4.
    The Shaggy sandwich.
    Meat. Cheese. Lettuce. Tomato. Bread. Repeat like 5 times. Completely implausible.
