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
When he's through
There's windows too
Then Nellie comes to see him
With a straight face she comes to see him
Taking her favourite pen from her pocket
She writes it down
The things that she's found
And he always sometimes gets a little nervous
But 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 there
She's glad that he cares so much
About the safety of electrical outlets
Taking her favourite 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
