School's Out (1930)

The kids mistake Miss Crabtree's brother for a potential boyfriend, and plot to discourage him.

The schoolchildren lost their last teacher because she got married and quit her job. When the brother of their teacher Miss Crabtree comes to visit, the children mistake him for a suitor. The children tell abominable lies about Miss Crabtree to try to discourage the man. Meanwhile, one of the children is selling answers to the upcoming oral exam. Unfortunately for the students, the young entrepreneur used a book of minstrelsy and blackface as his source for the "answers".
