Mr Monroe (Jim J. Bullock) is explaining infant care to his class using a rubber doll, when a paper airplane with a sense of direction starts buzzing his head. He swings the baby, hitting the skeleton next to his desk, shattering its head and sending it to the floor. In the next cut, the skeleton is standing up again, and Mr Monroe whacks it down again.
When Miss Enstile (Foreign Languages teacher) demonstrates Spanish pronunciation for her class, she says, "El muchacho en amor no se concentra (The boy in love does not concentrate)." The on-screen subtitle, however, says, "The boy in love must concentrate."
