Riley and Maya's new teacher decides to teach using a comic book, just like how Mr. Turner assigned an issue of X-Men on Cory's first day of high school. Mr. Turner himself makes an appearance in this episode.
Two girls open the door and say that they'll take on high school, and Riley and Maya open and slam the doors in their faces which is reminiscent of Cory and Shawn slam the doors in the faces of two males.
