This is the only episode in which John Stamos' mullet hairpiece was not for flashback sequences or old home videos. The storyline was set in the present and centered around Stepanie accidentally cutting off a chunk of Jesse's [actually fake] hair, a clever way to transition from John Stamos' mullet [that he cut off during hiatus] to his brand-new 'do.
In this episode Jesse's last name is Katsopolis he would retain this last name for the rest of the series even after he marries Becky who hyphenates her name to Donaldson-Katsopolis. In season one, his last name was Cochran. This is because of two reasons, one was because John wanted it changed to represent his own Greek heritage, and two it was because Cochran was a stage name for his band cause he thought it sounded more rock and roll.
The book that Joey is reading in Stephanie's pretend barbershop is "Horton Hears a Who!" by Dr. Seuss.
