Episode title spoken by Charlie, to Alan.
Two members of Judith's support group are played by actresses who also appeared in the sitcom "Mom (2013)": Yvette Nicole Brown (Mandy) played Nora in seven episodes as Christy's AA sponsor; and Amy Farrington (Kathleen) played an AA group member in "Wind Chimes and a Bottomless Pit of Sadness (2017)".
The T-shirt Judith wears during her support-group meeting is the same worn by Penny in "The Big Bang Theory"'s first and last episodes.
