And he sings when he mops   Seems to help him a lot   Where there's uneven stairs   Mr. Landlord is there      Well, he mops all day   Can't get away too long   And when he's through   There's windows too      Then Nellie comes to see him   With a straight face, she comes to see him   And taking her favorite pen from her pocket   She writes it down, the things that she's found      And he always, sometimes gets a little nervous   'Cause he'd like for her to stay for a day      Would you care for a drink   "This is business", says she   Tell me where are the vents   For these apartments      So they go upstairs   To inspect air   The air is good   It's really good up there      She's glad that he cares so much   About the safety of electrical outlets   And taking her favorite pen from her pocket   She writes it down, the things that she's found      And she always sometimes gets a little nervous   'Cause she'd like to stay with him for a day
