The house where Kimmy babysits Aaron is the same house previously used in Misadventures in Babysitting (1990) when DJ babysits Brian, just with different wallpaper, decorations, and door/trim colors.
The title comes from the 1983 song "Girls Just Want to Have Fun" written by Robert Hazard, and was the first major single released by singer Cyndi Lauper as a solo artist.
