Book excerpt: Everyone’s heard of Usain Bolt, but how many people know about Dineka Maguire? Like Bolt, the Irish woman is a world record holder but in the rather lesser known sport of bog snorkelling. She is just one of the hundreds of unsung heroes featured in this book chronicling the people who go to bizarre lengths to break world records in the weirdest categories; people who devote hours of intense training to spitting dung, eating cockroaches, sniffing feet or tossing tuna in the hope of one day being recognised as the best in the world. This astonishing compendium of the weirdest, wackiest and most disgusting world records will amuse and astound in equal measure. Entries include: Longest ear hair Fastest marathon while wearing a deep-sea diving suit Fastest bog snorkeller Farthest distance skateboarding by a goat Most bees on body Most milk crates balanced on head Fastest 5-km run while dressed as a penguin and juggling Heaviest airplane pulled with teeth Fastest shopping trolley Longest backwards motorcycle ride Most stairs climbed by bicycle Fastest 30 metres on a scooter by a dog First water-skiing squirrel
