There was a discussion here a couple of weeks ago about whether there is a specific parody of any part of "Taxi Driver" in "The Maid" (the whole prostitution angle). I watched both the movie and the episode in the past week, and there clearly is one small bit taken from the film: in "TD", DiNiro tries to pay Harvey Keitel (the pimp) on the street, Keitel steps back, hands raised and says, "Pay the girl." In "The Maid," Jerry attempt to pay the owner of the cleaning service (on the sidewalk), who steps back, raises his hands and says, "Pay the girl." (Note: both quotes are paraphrases.)
