When Addie shows Louis the house (early in the film), he has a glass of wine in his right hand and a paper bag with something in his left hand. Going up the stairs, he has the wine in his left hand and uses his right hand to hold on to the stair railing. Upstairs, the glass and the bag are back where they were before going up.
The title, if read out loud quickly, is a crude misinterpretation, out-of-keeping with the mood of the movie.
