Based on a few YouTube videos I see on the ladder vs stepladder, each chapter will feature two different characters.
It was a nice day at the Wright anything agency. Apollo was using a ladder to reach some high files to sort through them. When he was done getting the files he told his boss Phoenix, "There we go, I removed all the files from the highest shelves of the bookshelf, now let me just put the ladder away." Suddenly Phoenix said, "Apollo that is a stepladder you used not a ladder." Apollo said to Phoenix, "Mr Wright that is clearly a ladder, ladders are bigger than stepladders." Suddenly Apollo decided to step out for a minute. After coming back he decided to take out the ladder again to reach some old evidence from another shelf and when he was done with that, Apollo once again said, "Ok I'm done taking the evidence from past cases off the shelf now let me just put the ladder back." Phoenix said, "Apollo I told you before that is a step ladder not a ladder." Apollo said to Phoenix, "Look we had already had this argument, that is a ladder not a stepladder." After the argument, Apollo decided to go home for the rest of the day.
