The innocuously titled Who Am I? Where Did I Come From? is Dr. Ruth's attempt to teach kids about birds, bees, beaks, and stingers. Given the book's 3-D format, it's hard not to envision bulging paper dude bits on every page. But Dr. Ruth assured The Chicago Tribune that the work contained no R-rated representations. Specifically, she stated: "No member of the male sexual body pops up." However, it is worth noting that she insisted on having "a lift-the-flap page that reveals the difference between girls and boys."
