Boo! is a 1932 American Pre-Code comedy horror short film by Universal Pictures, directed and written by Albert DeMond. Boo! contains clips of horror films Nosferatu (1922), The Cat Creeps (1930), and Frankenstein (1931), mocking them thoroughly.

Plot

The film starts with a man (Morton Lowry) reading the novel Dracula. The narrator says that they are presenting their own formula for cheap entertainment, a nightmare. They say to eat a real lobster, not the kind they send to congress, have milk, and work up a chill. The man falls asleep.
