"Matthew?"
Yes, how can I help?
"What's the World's Largest Smoothie, mate?"
Funny you should ask that, reader. I have just found out the answer.
The world's largest smoothie was made in Canada last week. They used blueberries (we call them Bloobs, in the trade)
It was a little publicity drive by Dairy Farmers of Canada. Good for them I say. This is a fun way to promote your product when you have got a bit too much.

You have got to be kiddling me. I was in bloomin' Toronto, kicking my heels, trying to find something exciting to do and all the while this bloob masterpiece was being created? Fiddlesticks.
