The episode title is a nod to the tagline of Child's Play 2 (1990), released a year earlier: "Sorry Jack... Chucky's Back!"
Steve makes a reference to Child's Play 2 (1990), which features Christine Elise, who has a recurring role as Emily Valentine on this show.
Not only is the name "Chuckie" a play on the horror movie doll (which is what Steve basically thinks of the grown-up Chuckie), but the young TV-show Chuckie was played by Miko Hughes, known as one of the all-time creepy horror movie kids, from Pet Sematary.
