Gulp: Adventures On the Alimentary Canal by Mary Roach

A humorous, informative book about the science and false beliefs about the internal system that runs from your mouth through your stomach and out your butt.

Roach has become famous for her snarky, hilarious approach to often icky nonfiction subjects. This one's got a lot of ick in it - spit, farts, poop, digestion, and more - but she makes it worth the time by dispelling falsehoods, researching history, and interviewing scientists on the cutting edge.

I picked this for book discussion and we circulated a LOT of copies, so I'll be interested to see if anybody shows up to talk about it. For me, the chapter on Elvis made the whole book worthwhile.

Incidentally, I listened to the audiobook, read by Emily Woo Zeller, which was awesome. She helped convey the tongue-in-cheek way the book is written and the glee with which Roach often imparts her research.
