It may sound like a bumper sticker or a Flatulence Pride button, but is actually a book by Carl Japikse, subtitled "Writings of Benjamin Franklin You Never Read in School". A collection of the humorous and satirical writings of Benjamin Franklin, including his proposal for scientific testing of farting, as well as advice on selecting a mistress. The book brings up a side of Franklin that is rarely seen in history books: his good sense of humor, but I think the title of the book may be the biggest single reason for the sales (over 100,000 copies sold) of it anyway...
