Avocado hand was in the news a few months ago.
Apparently, instead of levering the stone out with a spoon, or slicing the avocado off the stone like a normal person would, apparently the hipster/Nigella/not sure which stupid person publicised it was way to do it is to hold the avocado half with the stone in it in one hand and use the other to ram a large knife into the stone to pull it out that way.
What could possibly go wrong except to miss the stone and ram the knife straight through the soft avocado into your hand?
So instead of going back to chopping up avocados in a sensible and non trendy way, possibly publicised by a 1970s style graphically frightening public information film, the modern way is to fuck with avocados to grow them without stones to protect the stupid from themselves.
