Query: Most hilarious and resourceful book

I loved it! I thought the colorful illustrations were hilarious. The book not only entertains, it provides the reader with useful research information. Amusing sidebars poke fun at the primitive waste-disposal methods that prevailed through the ages. Readers will also be amazed to discover that baths were considered unhealthy during the Middle Ages and the Renaissance. It was not until the discovery of germs in the mid-1800s that the importance of cleanliness was recognized, and it wasn't until 1851 that the White House had a bathtub with running water. My only concern about the use of this book within the classroom would be the colorful illustrations of naked peoples backsides. The language of the book was very easy to follow and comprehend, which would benefit students ages 5 - up.
