Milhouse's mother, Luann Van Houten, makes her first appearance in this episode. She was designed to look very similar to Milhouse. Maggie Roswell was assigned to voice the character and she originally based it on Milhouse, who is voiced by Pamela Hayden. The producers felt her impression sounded out of place so she ended up using a more normal sounding voice. It was Gewirtz who in this episode gave Milhouse his last name, Van Houten, which he got from one of his wife's friends.
