The name of the department store security guard who picks up the matches is "M.C. Guffin", visible in reverse in the mirror as he puts the matches in his pocket. McGuffin or MacGuffin is a term for an object in a film which the characters want and which drives the plot - in this case the matches and the list they contain.
The name of the maintenance man who found the matchbook is "Guff", one of several references to "McGuffin" in this episode.
The name of the hotel maid is Mrs. McGuffin, one of several references to a "McGuffin" in this episode.
The store security man's name badge is shown to us in a reflection in a mirror. The right way around, it would read "NIFFUG,C.M.". Similarly, the janitor's name is "DUFF", on an in/out status board. Tape making the "D" is coming unstuck to make it resemble a ¨G"; his name is next to a member of housekeeping named "MAC"; and he changes his status from "IN" to "OUT". Only the housekeeper is in fact truly named "McGuffin", in dialogue when she is addressed as "Goodnight, Mrs. McGufin!". Possibly, she is the "MAC" of the status board.
The boy in the lift pressing all of the buttons bears a striking resemblance to the Mad magazine incarnation of Alfred E. Neuman.
