Le Journal de Mickey #1778

In "Mauvais perdant !", Donald Duck and his nephews—Riri, Fifi, and Loulou—go head-to-head in the chaotic "Screwball Derby," a wild cross-country horse race where every trick in the book is fair game. With mud, mayhem, and stubborn pride on the line, the rivalry heats up as each competitor pushes the limits to stay ahead.

When Uncle Scrooge brings in the "Robot Computer Model XZ54"—affectionately known as "Mr. QED"—to streamline his operations, the plan seems flawless… until the machine starts taking over in ways no one expected. With Donald Duck and the nephews watching in disbelief, the office soon feels less like a workplace and more like a robot-run fortress.
