A Chump at Oxford (1940)

With Stan in drag, the boys get jobs as a butler and maid for a dinner party at the Vandevere's. After that ends in disaster, they're reduced to sweeping streets, and accidentally capture a bank robber. The grateful bank president sends them to Oxford for a proper education. There they become victims of student pranks, getting lost in the Maze and taking over the Dean's quarters as their own. But then a knock on the head gets Stan to believing he's the famed Lord Paddington, scholar and athlete extraordinaire. Suddenly erudite and supercilious, he retains Oliver as his valet, "Fatty."
