Seed of Chucky (2004)

Revealing mistake: When Tiffany calls Ruth Bailey, you can see that the mobile phone she uses is turned off.

Tiffany: I'm not getting pregnant again, I'll tell you that much. My mother always said, "Once is a blessing, twice is a curse."
Chucky: Well, that would explain your sister.

Trivia: Chucky's gender-confused child is called either "Glen" or "Glenda" depending on who is addressing him. This is a reference to the docudrama "Glen or Glenda" directed by Ed Wood about cross-dressing and human sexuality. Wood was famously a cross-dresser.
