Skateboarding dog breaks world record

On Thursday, Guinness World Records Day, tens of thousands of people were hoping to make it into the record books.

Organizers say as many as 650,000 people participated.

One of the most celebrated attempts came from English Bulldog, Otto, who set the record for the "longest human tunnel traveled through by a skateboarding dog."

Otto skated through the legs of 30 humans in Lima, Peru, "without being led or touched," Guinness confirmed.
