Funny world records

From the world's youngest woman with a full beard, to the world's largest domestic cat, the Guinness World Records (GWR) of 2017 have been unveiled.

Pictures and stories of the new record breakers were revealed on Friday after months of research and scouring the globe looking for the "best of the best", the GWR statement said.

"It's been another outstanding year for record-breaking," editor-in-chief of GWR Craig Glenday said.

"We've been able to pack the new book with 4,000 records — 80 per cent of which are new."

Among the record holders is body positivity campaigner and catwalk model Harnaam Kaur, 24, who took out the title for the youngest woman in the world to have a full beard.

Ms Kaur, from Slough in England, said it was "absolutely humbling" to be included, saying she overcame years of bullying to take ownership of her appearance and achieve this record.

The 2017 list also includes a record for the highest jump by a llama, which was taken out by nine-year-old Caspa from Porthmadog in Wales.

Caspa has been with his owner, Sue, since he was two years old. She described the llama, who is able to clear a 1.13-metre high bar, as "a total diva".
