That's a pretty big, but not the biggest, pumpkin

Oh, yes, pumpkins can be some really big squash, and this one sets a new record weight in the UK.  TPP's Father once grew a pumpkin that was just a couple of hundred pounds, and it was huge.  TPP saw one at the Great Pumpkin Patch that was just 900 pounds.  Better have a big garden if you want to try to grow one of these.
