The QI Elves are the clever clogs researchers behind the smash hit panel show QI. Every Wednesday they appear on The Zoe Ball Breakfast Show and they answer the ponderings and wonderings of BBC Radio 2's most inquisitive listeners. Why isn't a unicorn called a unihorn? Who first put the alphabet in alphabetical order? How much water would you need to put out the sun? When, and exactly why, did salted caramel ice cream become so popular? This book features the QI Elves' answers to 200 questions on topics ranging from goosebumps to gherkins and everything in-between. Generously sprinkled with mind-boggling extra facts from the Elves, this is essential reading for the incurably curious.
