In this episode the word Brown-Out is used instead of the word Black-out.
Doc's purple shirt is white just as Doc yells at Biff for pouring soda over the generator, then is back to its normal purple afterwards.
The statue of the Pioneer has never been seen in Courthouse Square before this episode and is never seen afterwards!
Bullies (to Verne): Daddy is a genius, Daddy is a genius, there's lots of space, behind his face, because his brain's on Venus!
Ralph (Biff's friend): I say, we destroy what we don't understand!
The Browns have all dressed up as geisha.
Doc (high pitched): Nobody here but us geisha!
Verne: Want a massage, geek-san?
Biff: Uh, no thanks honey. Uh-uh, miss.
Clara: Emmett Lathrop Brown. Scientist, husband and father; or just another name for disaster?
Clara: You just work out in the lab and we'll holler when something else needs ruining.
Doc: Ah, Clara, you're so cute when you're sarcastic.
This episode was released on the VHS entitled Back to the Future: Go Fly A Kite and Hill Valley Brown-Out.
Jules is a lot more confident in this episode than he was in "The Money Tree". In that episode, Jules had no friends, but got some at the end. Maybe, like with George McFly in 1955 during the events of Back To The Future Part I, having friends has made Jules more confident in himself and thus able to stand up to the bullies and protect his younger brother. A nice little insight on the character of Jules here.
In this episode there is a statue of the "Old Pioneer and his Mule" in Courthouse Square. The Old Pioneer was the founder of Hill Valley back in 1850. In the original draft for Back to the Future Part II, where instead of 1955 Marty and Doc have to go to 1967 to get the almanac off Biff, this statue is "seen", and we discover that the pioneer is called Bill Hill. They reused this idea for this episode.
The Hill Valley Theater is showing a film called Back to the Future in this episode!
