After Michael orders refills at the bar, his drink changes into a Cosmopolitan and the levels of their drinks change as well.
Mothers' names on marriage certificates are typically required to be maiden, rather than married names; thus, for Maeby's mother, it should have listed Lindsay Bluth, not Lindsay Fünke, and George Michael's mother Tracy would not have been listed as Tracy Bluth. Her maiden name was not otherwise revealed.
The marriage certificate lists the address as "1 Lucille Lane / Newport Coast, CA 92606". The ZIP code 92606, however, actually lies in Irvine, a neighboring city of Newport Beach (of which Newport Coast is a part).
When Michael and GOB are speaking in the hotel room, a crew member briefly walks into the scene in the background.
According to the marriage certificate, George Michael was born on November 2, 1990 and Maeby was born on September 22, 1990. However, in "Hand to God", George Michael said that he was older than Maeby, and in "S.O.B.s'" he says his age is 16 when introducing himself at his new school. Also, this would make their characters only 15 years old in this episode, which contradicts information given in previous episodes.
