Danville High School is the high school in which some of the series' teenagers study.
In the episode "Brain Drain", Vanessa had a flashback to the last time her dad picked her up. Doofenshmirtz picked her up from school, in a wagon, wearing a baby's outfit, embarrassing her in front of all her friends.
In the episode "Doof 101", Vanessa went back to school again for the first day of the year and Doofenshmirtz turned out to be her new teacher. Doofenshmirtz wanted to teach the class and be a good guy, but Vanessa thought it was embarrassing that he was there. The episode mainly focused on him, trying to turn the mutated Johnny back into his normal self again, while still trying to stay under the radar of Principal Lang.
