Don Ramón, working as carpenter, hits his fingers with the hammer all the time. Meanwhile, the kids decide to play carpenters. Then, they hit Professor Jirafales with the hammer all the time. Chespirito is in a cast which I'm 99.9% sure it's real because in an episode of Chapulin Colorado in the same time also has a cast. "Coincidentally" in the Dr. Chapatín short in this episode he also has the same cast.
