Over 120 million copies of the Guinness World Records book have sold around the world and the 2013 version is now available, with the usual collection of incredible people and feats on show

Here's a new take on the saying 'welcome to the gun show'. Moustafa Adel Ismail has the world's largest biceps and triceps; his right upper-arm circumference is 63.5 cm (25 in) flexed and 60.96 cm (24 in) non-flexed, and his left upper-arm circumference is 64.77 cm (25.5 in) flexed and 62.23 cm (24.5 in) non-flexed. Moustafa, trains six days a week and eats six meals a day, said: "I have been working out for the last 11 years to get muscles this big". He hopes his newfound fame will be the springboard to become a professional body builder and plans to compete in "naturally enhanced body-building competitions".

Tallest Donkey: Oklahoma Sam (USA) - 155.45 cm (5ft 1 in)

A mule named 'Oklahoma Sam' is today celebrating being crowned the 'Tallest Living Donkey' on the planet. Measuring 15.3 hands (155.45 cm; 5ft 1in) tall, she dwarfs the common donkey (8 hands high) and her own larger 'Mammoth Jackstock' breed (12 hands high). Sam's overall care is handled by 54-year-old Linda Davis, a keen gardener and animal lover. Linda, who calls Sam her "soul mate", says: "It actually doesn't cost anymore to have a donkey of this size. He doesn't eat more. In fact, if I give him more bale he'll just use it to make his bedding more comfortable. He loves his sleep."

Tallest Dog: Zeus (USA) – 111.8 cm (44 in)

Just look at the size of this dog. Zeus is a 3-year-old Great Dane from Michigan and measures an incredible 111.8 cm (44 in) from foot to withers: the same size as a donkey. Standing on hind legs, Zeus stretches to 7 ft 4 in and towers over his owner Denise Doorlag. Denise said: "Zeus is an awesome dog," says owner Denise. "The only downside is that everything costs more; the food, medicines, transport. We had to get a van to be able to transport him, and if he steps on your foot- he leaves bruises."

Zeus breaks the record of previous record-breaking pooch Giant George, who is 1-inch shorter, which makes Zeus the tallest dog ever recorded in history.

Shortest Bull: Archie (Northern Ireland) – 76.2 cm (30 in)

Archie, a 29-month-old Dexter from County Antrim, Northern Ireland, is today recognised as the Shortest Bull in the world. He measures just 76.2 cm (30 in) from the hoof to the withers, 15 inches shorter than other bulls of his breed (typically 45 in). His height means that he's dwarfed by the other animals at his farm, including even the dogs and goats.
