Once enrolled, Steve tries to speak with Caroline, but she refuses to listen to his explanations and tells him she is seeking an annulment. Later, in music class, stodgy Professor Hendricks attempts to discredit Steve, whose presence on campus has created a furor among the co-eds, by ordering him to write his own version of the Scottish ballad "Loch Lomond" and teach the next day's class. With help from several talented students, Carlos, the music teaching assistant (Ethel Smith), and Steve's friend Harry James and his orchestra, Steve meets Hendricks' challenge and is awarded an "A." That night, Steve visits Caroline at her house, but is turned out after Willis Evans, a conservative botany professor who is in love with Caroline, arrives. When Caroline realizes that Steve is hiding in her closet, spying on her, she commands Willis' Great Dane to guard the closet door, while reminding Steve that unless he is in his room in five minutes, he will be expelled for breaking curfew. With only seconds to spare, Steve manages to trick the dog long enough to escape back to his dingy basement room. Steve is then visited by George, who threatens to vilify him in the press unless he finishes his songs. When Steve swears deadly revenge on the person who hired Maria, however, George backs down and offers to help Steve do his homework. Concerned about the approaching Parents Day, Dean Clinton, meanwhile, commands Steve's professors, who have penalized him with only fifty-five demerits, to bear down on him. To that end, Mme. Zarka, Steve's ruthlessly strict ballet teacher, forces him to wear a tutu and dance with the co-eds, but Steve once again rises to the occasion. A now desperate Dean Clinton asks Caroline to go out with Steve and ensure that he arrives back at Victoria after the curfew. Caroline agrees, but during the evening, Steve convinces her of his innocence, and as they drive back to school, the newlyweds make plans to return to California together. Unknown to Caroline and Steve, Maria is on campus, looking to expose George, who has been trying to get rid of her, to Steve. At the same time, a campus sorority descends on Steve's room, hoping to initiate him, and Jean Allenwood, another co-ed, shows up with news that her parents and Dean Clinton are on their way over to inspect his room. As Steve desperately hides all the women in two closets and keeps Caroline from discovering Maria, George unexpectedly arrives. Although Steve succeeds in hiding George and himself and fooling Dean Clinton and the Allenwoods, Maria soon makes her presence known to Caroline, who once again leaves in a fury. Later, Steve promises to write songs for George's water ballet show on condition he make Caroline the star. George agrees, and after Maria is finally able to tell Caroline the truth, Caroline happily reunites with Steve, who then gives George a thrashing.

In one sequence Red Skelton's character is trapped inside a house by a large dog. He escapes by removing the hinge pins from the door, picking up the door and, as the dog comes inside he holds the door between them and goes out. Red said that they had written themselves into a corner and could not come up with a way for him to get out. They were going to scrap the scene when the comedian Buster Keaton visited the set, took one look and told them how to do it.
The scene has been parodied several times, most famously in The Great Muppet Caper (1981), with Miss Piggy, briefly in the "Be My Guest" sequence in the Disney movie Beauty and the Beast (1991 film) (1992) and in The Simpsons episode Bart of Darkness (1994), with Lisa Simpson.
