A new world record was set in Edinburgh after an American completed 206 jumps on a pogo stick in one minute.
Ashrita Furman and a canine companion completed the feat
Shopkeeper Ashrita Furman carried out the attempt next to the statue of Greyfriars Bobby, while carrying a dog.
Mr Furman, who has the highest number of Guinness World Records, had to complete in excess of 173 jumps - more than two per second.
He now holds 102 records and said he was already planning his next stunt.
Mr Furman has been up Mount Fuji on a pogo stick, bounced a mile on a space hopper along the Great Wall of China and pushed an orange at speed with his nose.
He also holds records for backwards cycling, an underwater pogo attempt and most hop-scotch games in 24 hours.
The record breaker insisted the dog, which he carried in honour of the legendary terrier who stood guard by his master's grave, was unharmed.
Mr Furman - who also has records for balancing a huge stack of beer glasses on his chin, using the world's largest hula hoop and somersaulting - added that dogs he had used in training seemed to enjoy the experience and had, literally, leapt to the challenge.
However, he had asked for a vet to be on stand-by in an effort to reassure onlookers.
After his success, Mr Furman said: "The editor of the Guinness book is Scottish and he said 'now listen here, you've been around the world and you have not broken a record in Scotland'.
"So why not break a record in Scotland?"
