Butter Face is the name of a short film directed by Dale Squires mentioned in the episode "A Film by Dale Squires". Tori says that she has watched it like a million times on the Internet, and Jade remarked "Who hasn't?" implying that it is a very popular and a very well-known short film.
It is said that "the man's wife" does not appear in the ending scene, which everyone seems to think was a brilliant idea. However, she was actually not in the scene because the actress had food poisoning and was vomiting in the bathroom. Not much is known about what takes place in the movie other than this.
