This reminds me of a little book my parents had entitled "Dear Sir." It was a collection of letters sent to the census bureau, draft boards, ration control boards, and other government agencies just before and during WWII.
The only ones I can remember are from the census questionnaire:
Q: Are your children boys or girls?
A: Of course. What else?
Q. How many adults reside in your household?
A: Two adults and two adultresses.
