A sound editing error. At the 15:50 mark, as the genie sits on the stairs lighting a cigarette, the end of the genie's line "...taxes involved" is repeated when there's a cut to Arthur Castle getting up from the floor below to confront the genie. The same words, "...taxes involved" are repeated over this shot. This happens when there isn't a clean separation between one performer's line delivery and the other performer's line delivery. When the lines overlap, the editor gets stuck having to use the overlapped sound from the off-camera actor's line delivery leading in to the next shot's on camera line delivery of the other actor.
