In "Boys Do Cry", Chris says that trespassing onto George W. Bush's home at Crawford Ranch is kinkier than porn for senior citizen porn. A scene from one of the films begins with a woman asking a just as elderly male friend if he is wearing new slacks. After he walks into the house accompanied by sexy music, he forgets why he came, and the woman asks once more if he got new slacks, in a tone that displays her failing memory.

In "Road to Germany", Stewie mentions that leaving Mort Goldman in a past time would be more irresponsible than silent movie porn, as it immediately cuts to a scene in a black and white movie of a man and a woman lying in bed. The woman asks if the man brought rubbers, to which he replies he did, as he takes out a pair of rubber boots and proceeds to dance comically with the woman.
In "Baby Not On Board", Stewie looks inside Chris's porn magazine, eager to see what a vagina looks like. When he takes a brief look at a page, he is instantly traumatized into gunning the magazine to shreds.
