During the dinner with Glenn's father, Glenn says, "this corn is special" when the conversation becomes uncomfortable and Glenn wants to change the subject. This is the same phrase used by Ned Beatty in Deliverance (1972) to change the subject at the dinner table when Jon Voight begins to cry in front of the mountain people.
First appearance of Glenn's father Dan Quagmire and the only episode where he is referred to as such as he undergoes a sex change operation and becomes Ida Davis.
