Oh, my!  When I looked up this book on Amazon, I learned that people who buy this book also have bought others like it.  Really?  And I never knew such books existed?

The Bathroom Guest Book ~ by Jack Kreismer, humor, 2000

This one has "Privia" to read, like this:  "The Scott Paper Company, makers of the toilet tissue, once conducted a survey which concluded that more than two-thirds of people holding master's degrees or doctorates read in the bathroom."

Our Restroom Guest Book: Something to Do While You Do What You Do ~ humor, 2012

Each page includes hilarious checkboxes including  things like:  favorite name of bathroom, rate your experience, and check all that apply.  I like the "How do you hang yours?" question about toilet paper:  Over, Under, or Lazy.

Do I plan to buy any of these?  No, but they are good for a laugh today.
