Before he was teaching kids to read, Dr. Seuss was teaching soldiers how to avoid malaria.

He was probably too busy as a U.S. Army captain to bother finding anything to rhyme with "malaria," but the good Theodor Geisel did take the time to personify the Anopheles mosquito as a vixen named Ann out to tempt unwary soldiers into an undignified death. In his typical whimsical style, adjusted to a slightly older audience, he warned young G.I.s to keep their pants (and the rest of their clothes) on: "If you go running around as a strip teaser, you haven't got a chance."
