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."
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.
