In "Lyon of Scrimmage", the Mad Cows went up against them. They took a pounding for the first half of the game, but with the Semi-Pros needing only one more point to win, Adam kicked his game play into high gear, by stuffing Jake into his uniform, allowing them to even things out. They made the final decision to trick the Semi-Pros, by making them think Henry was a football, which cost them the Semi-Pros the game.
The victory of Charles Darwin Middle School and defeat of the Semi-Pros was still remembered and went down in history as their famous game was mentioned again in "Where in the World Are Adam's Parents?".
