Artie Ziff is shocked to learn that Marge Bouvier is married. Yet in the previous scene, he referred to her by her married name, Marge Simpson. During season 4, Artie also ran into Homer and Marge at their high school reunion.
Artie Ziff is seen sitting next to a large picture window overlooking Silicon Valley while searching his e-mail. When he sees the e-mail from Marge, the camera angle changes and the window is gone, and we see Artie completely surrounded by photos of Marge.
