Peter breaks the fourth wall twice; once when he recognizes his horse as being voiced by Gilbert Gottfried and starts talking directly to the actor instead of the horse, and once at the end when he directs the moral of the story to the audience.
There's a scene where Peter sees a model in a red sports car next. The scene is a gag from the original Vacation film but ends with the car getting hit by a semi and then exploding. The same scene can be seen in the 2015 version of Vacation where Rusty sees a beautiful woman in a sports car to then get hit by a semi to then explode.
The episode features a guest performance by Camilla Stull, a 12-year-old leukemia patient who voiced one of the beauty pageant contestants on behalf of the Wish-A-Foundation. Although Stull passed away in 2007, the creators expressed pride that they able to "immortalized" her into the episode.
Stewie would be too young to take communion. [Even if he was five/six, instead of a character who has been one for five seasons]
When Brian said would like some change please for you it was a Hindi accent so he was referencing Apu from the simpsons 1989
