Thousands of twins packed two-by-two into a stadium in Sri Lanka’s capital on Monday – so many that officials struggled to count them in time to prove they had organized a record-breaking gathering. Huge queues built up at the open-air venue in Colombo as sets of siblings waited to get their birth certificates checked. The last record was set in Taiwan in 1999, when 3,961 sets of twins, 37 sets of triplets and four sets of quadruplets gathered outside Taipei City Hall.
