You could apply these not just to fans, but to coaches as well, and unfortunately a couple of officials that I've worked with.
Side note: A good number of coaches are really latched on to the "If the defense ever touches the ball there can't be a backcourt" myth. It seems like every time I call "last to touch, first to touch" as a BC violation on the offense, I get that argument from their coach that "The defense touched it!".
