Background and release The characters Megin and Greg are based on Spinelli's real life children Molly and Jeffery. Leo Borlock, who would later be the narrator in Stargirl is mentioned in this novel as a person who everyone goes to for advice.The following passage from the novel Who Put That Hair in My Toothbrush? (1984, by Jerry Spinelli): "I even thought of Leo Borlock. A lot of kids - mostly girls, actually - go to him for advice" (Spinelli 21). It could be the same Leo from Stargirl, which would make sense due to him not appearing in the sequel. There are three main book covers for this book.
