Every Wednesday on The Zoe Ball Breakfast Show, BBC Radio 2's most inquisitive listeners get to put their questions to the QI Elves. The questions are wonderfully original, often silly and sometimes quirky, and the QI Elves' answers are always fascinating and frequently hilarious.

From spiders to stinging nettles, bees to by bands and twins to thermal undies, you'll wonder why these questions hadn't occurred to you before - but you'll never forget the answers and will want to share them will all your friends.

Funny You Should Ask Again . . . is a must-read for the incurably curious.
