The whole procession is ultimately ruined when Ernest realizes he cannot recharge and has to direct the band with his usual mind and intelligence.

He spends the whole disastrous affair with his head inserted in a tuba which resulted after he descended toward the band from the podium in his clumsiness, ending up causing a series of catastrophic events and disappointing everyone in the whole school, especially the principal and Ms. Flugal.

Depressed, with the knowledge that he cannot recharge his head anymore, Ernest starts packing his things until he finds three of his friends mocking him.

On the day of the big exam, Ernest is about to go in, but before he does, the scientists return and tell him excitedly that the brain accelerator has been repaired.

While Ernest is leading the halftime show with his unique routines, four band members are able to sneak off to try to prevent the fix from going through.

With the help of the two science teachers, they infiltrate the locker room with sleeping gas, effectively replacing the football team to win the game themselves.

In the midst of the celebration, the football players arrive from the locker room in bewilderment and the board chairperson is informed of the inspector's actions and intentions and the coach's involvement.

It is also revealed Ernest passed the final exam, so he earns his high school diploma and is permitted to keep his job.

The film received a limited theatrical release in Cincinnati, Ohio on June 10, 1994, and in Louisville, Kentucky on July 29.
