Minkus: Hey, Mr. Turner. Wait up!

When Eric climbs out of Feeny's window, the "Good-Looking Guy" song from Hair Today, Goon Tomorrow, is played.
Topanga and Minkus count A's to see who is the valedictorian. They have 700 and 699 A's respectively. In order to have that many A's, they would have to be counting every test and quiz grade given. This is highly unrealistic. as most schools use grade point averages to chose valedictorian.
Alan, Amy and Morgan leave while Eric is singing, but when Cory gets his diploma, they in the audience again.
During the ceremonies, Eric is still holding the microphone, and Mr. Feeny is talking into the empty microphone holder. However, he has an amplified voice.
