When their math teacher Mrs. Westlake (Sonia Braga) goes to the hospital to have her baby, Theo (Malcolm-Jamal Warner) and Cockroach (Carl Anthony Payne II) wonder if they will be spared an upcoming math test. The "answer" arrives in the form of a substitute teacher, leading to a surprisingly serious monologue from the usually insouciant Cockroach! Meanwhile, Denise (Lisa Bonet) comes to the rescue when Vanessa (Tempestt Bledsoe) gets a zit, and Rudy (Keshia Knight Pulliam) tries to master a bike with the nervous assistance of Cliff (Bill Cosby). Fashion model and future Jamie Foxx Show regular Garcelle Beauvais appears unbilled as a nurse.
