Opening Credits Outfit: Sabrina changes into a 1950's pink poodle skirt and white sweater and says, "Grease is a word. Not the word." This outfit resembles one the many that girls wore in the movie Grease (1978).
In the German version, when the Violent Femmes are watching the TV, the actual German dub of 'The Ren and Stimpy Show' isn't used. Kai Taschner voices Ren instead of Ren's usual voice, Santiago Ziesmer.
While watching 'The Ren and Stimpy Show', one of the Violent Femmes says "This is my favorite part". Logically he would be referring to the part in the episode where Ren collapses in tears over Stimpy leaving for Hollywood.
