When Lisa (Marlyn Mason) asks Oscar if Felix is into sports, he answers that Felix' idea of sports is the Betty Crocker Bakeoff. In the Season 1 episode "They Shoot Horseradish, Don't They?", Felix competes in a cooking contest in which his main rival is Barbara Arcola, aka Bernaise Barbara- also played by Marlyn Mason.
The title is a parody on the common expression: I don't believe in rumors.
Felix alleges that his I.Q. happens to be 186.
