This program was originally titled "You're Elected, Charlie Brown", a phrase Linus actually speaks early in the show. At the last minute during production, the word "Not" was added to the title, in deference to the fact that the plot actually focuses on Linus' run for student body president. This explains why there's a carat with the word "Not" on the blackboard and why the chorus still sings "You're elected, Charlie Brown".
Animated debut of Snoopy's alter ego Joe Cool.
The name of the school the gang attends is Birchwood School.
Vince Guraldi himself sings the "Joe Cool" theme, one of the rare moments he lended his voice to the music he created for the Peanuts specials, the other being "Little Birdie" in "A Charlie Brown Thanksgiving" from 1973.
Based on a series of strips from October 1964.
