Stiff is incredibly informative and yet incredibly funny, all while covering a topic that most people would not find the least bit humorous: what happens to human bodies after death? Mary Roach fearlessly explores every angle of being dead, from anatomy labs to ballistics testing centers to mummification. The research is clearly thorough and painstakingly put together, but presented with the matter-of-fact delivery that is the author's trademark. 
 Updated to add: Maybe not the best choice if you like to read while you're eating...
