The episode's title is a reference to the 1994 film, "Dumb and Dumber". In this episode, Henry quotes, "She's as common as an angry woman in an Ibsen play," perhaps referencing Nora in "A Doll's House". The revelation that Maggie is only smart because she is watching Lisa is similar to the case of Clever Hans at the turn of the century. During the second interview Henry calls Maggie "Pippi Nontalking", which is reference to the character Pippi Longstocking. Maggie as a genius talking through the phonics frog perhaps is a reference to Stephen Hawking communicating through his computer.
