American Dad! Season 4 Episode 11

After Roger sees Stan bathing with his mother, Francine tells him "I told you it was complicated", referring to Stan and Betty's relationship. Roger then replies "No, no, changing planes at O'Hare is complicated."

Psycho
Stan's actions of abducting his mother's dates may be a reference to Psycho, where Norman Bates killed his mother and her new boyfriend out of jealousy after she started dating.

Roger's disguise while Betty visits is Cousin Oliver from the Brady Bunch, although he calls himself "Phil" instead of "Oliver".

Only the Lonely
The whole mother-and-son relationship between Stan and his mother bears similarities to the relationship between Danny Muldoon and Rose in the 1991 movie Only the Lonely, as Herkules can be easily identified as a tongue-in-cheek reference to Nick Acropolis (interpretated by Anthony Quinn).

Episode Title
The title takes from the Greek play of Oedipus in which the title character kills his father and marries his mother, this is in relation to Stan's actions in killing his mother's boyfriends to be close to her.

Stan: (singing) Wash, wash, wash your VJ...
Stan's song about bathing his mother is done to the tune of the old sea chanty "What Do You Do With A Drunken Sailor".

Betty: ...Adam Sandler had a remote control, I don't know what was happening.
She is referring to the 2006 movie Click, where Adam Sandler gets a remote control that can control his life.
