Doug: The Giant Non-Potato

A couple from Hamilton, New Zealand thought they had found the world's biggest potato. They christened their 7.8 kg tuber 'Doug' and sent their claim off to the Guiness Book of Records. A DNA sample from 'Doug', however, has now revealed 'he' is the tuber of a gourd (https://www.theguardian.com/world/2022/mar/16/giant-new-zealand-potato-is-not-in-fact-a-potato-guinness-world-records-rules). 'Doug', apparently, tasted like a potato but is of the wrong species. 'He's' not a 'chip off the old block', as they say. So, the UK retains the current record at just under 5 kg.
