Johnny mentions the movie Ladybugs (1992), in which Jonathan Brandis dresses up as a woman to play soccer. William Zabka starred in Just One of the Guys (1985), where a high school girl pretends to be a boy. In that movie Zabka portrays a bully, and there's even a comment that the girl looks just like Ralph Macchio from The Karate Kid (1984).
In the previous season, when Miguel suggested Johnny should upload more photos in his Facebook to impress Ali, Johnny suggested he should oil up, to show off his muscles. Here, Johnny makes Miguel oil up and flex his muscles to attract female students.
Johnny mentions Ladybugs and a coach who can't get any respect. This is also a reference to Back To School, which starred Rodney Dangerfield and had a William Zabka supporting role.
