At the start of each episode after a few scenes, we would hear Doug's footsteps, opens the door and turns on the light to reveal his name. He even says, "That's me." But then Porkchop got an idea to liven up the title. So he ran to get some paint, and quickly wrote the rest of the episode's title. But Doug didn't like it and said, "HEY!" So he chases after Porkchop. In the midst of the chase, various events occur before the light goes out and the episode continues. The following are categories of what Doug & Porkchop did at the end of the episode title scenes.
NOTE: The title scenes in Disney's Doug were more tamer, plus they sometimes involve some of the other characters.
