There are a couple of really bad ones on youtube that feature a 'gardening expert' using a broadfork like a harpoon and one that has some body builder guy in a meat suit, shirtlessly pounding a goalpost sized broadfork into apparently rock hard soil with his considerable hulking frame, 'wrasslin' style.
Now you can see skinny-armed Gulland showing a much more reasonable technique that will allow you to use a broadfork for hours on end if need be.
I'll apologize in advance for the less than Hollywood level of video, but movie making is about my 9th language. There will be more eventually, but I finally got the ball rolling with this one.
