When I was a teen, idk 15 or so, was just walking back to my house from the non-fenced backyard. Noticed my shoe was untied, noticed an old steel dolly nearby. Dolly was laying upside down, tongue up ...so I had the great idea to use the extra height of the dolly so I wouldn't have to bend down all the way....well I learned about levers that day ..the top handle came screaming for the top of my head and then I just seen stars while on my but.
