Trivia

 * Before Kathryn Mullen got the role of Jack's mom, singer/songwriter Cathy Richardson was considered for the role. She ended up being replaced by Mullen due to Richardson already doing Mary's voice in the pilot and later making on-screen appearances in season 1.
 * Mullen originally didn't like doing the role of Jack's Mom, but soon found it enjoyable when she was informed she could improvise with the role and play around with the script during the cold openings and endings of each episode.
