What makes French kissing “French”? Who played the first game of Spin the Bottle? What compels millions of tourists to kiss the Blarney Stone? And—most importantly—what does Julia Roberts look for in a good kisser? The answers to these questions can be found in Kiss and Tell—an irreverent miscellany of trivia drawn from science, art, ancient history, pop culture, and more. Here’s everything you ever wondered about kissing, including: •Why do princesses kiss frogs, anyway? •Who made “XO” shorthand for “hugs and kisses”? •Why do people kiss under mistletoe? •Is mononucleosis really spread by kissing? Best of all, Kiss and Tell features illustrations and photographs of famous kisses through history—everyone from the ancient Egyptians to Britney and Madonna. It’s the perfect Valentine’s Day gift for the know-it-all in your life—and also a terrific bedside reader when there’s no one around to smooch.
