If The Photograph Below Looks Familiar,

it is because it is in the Guinness Book of World Records,

it is of Peter Glazebrook (UK) at the National Gardening Show at the Royal Bath & West Showground in Shepton Mallet, Somerset, UK, on 4 September 2011, with the worlds heaviest potato weighing in at 4.98 kg (10 lb 14 oz) as recognized by Guinness, but there is now a new contender on the block, or should I say plot?

photographs MARK TAYLOR/STUFF, Donna and Colin Craig-Brown with Doug, their possibly-world-record spud, the couple weighed the spud and found it was a massive 7.9kg – so heavy you wouldn’t be permitted to take it on an aeroplane as carry-on luggage, 

Colin and Donna Craig-Brown said they initially weren't even sure of what they had discovered under a few inches of dirt in their Waikato garden, "I said to Donna this must be one of those white kumara that we grew," Colin Craig-Brown told Stuff.co.nz, "because some of them just grew massive here." Craig-Brown said it only after he stabbed at it with a fork that he discovered the item was a potato, "I said to Donna, 'It's a potato,' and she went, 'No.' I said, 'Yeah it is!'" he recalled to Newshub, well it looks like it is going to be a new world record, unless you have one that is bigger!
