When aired on Adult Swim on Cartoon Network, the opening sequence is cut short, meaning, the "Journey Through the Woods" part of the opening scene (from when the beaver chews down the tree with the "PEE-WEE'S PLAYHOUSE" sign on it, to when Pee Wee walks up to the front door, either knocking on it (or opening it in later seasons).) The part that took place INSIDE the playhouse where everyone was bouncing around to the upbeat beginning title song was omitted. After Pee wee is at the door and the mellow music ends, it just cuts right to the show.
