An Australian family has just claimed their second Guinness World Record by stringing over half a million Christmas lights across across their property. Lawyer David Richards and his family started decorating in October, which makes sense when you realize that they’ve strung 31 miles worth of lights. The total number of bulbs? 502,165 — and no, the Guinness Book of World Records didn’t feel the need to verify that number by counting them one by one. They used a combination of sales receipts and counting the number of strands to reach the total.
