Our house used to have a patio over the garage that had to be shoveled off by hand. My brother had thought it funny to hit me with snow from the snowblower in the previous storm. I was shoveling off the patio and he was using the snowblower to clear the driveway. He had pitched a fit about wanting to use the machine instead of the shovel, so I let him to avoid a fight.
Now, you are probably seeing where this is going, but don't beat me to the funny part. First: no, I did not dump a shovel full of snow on his head. I put the shovel on the ground and got a big run up to the edge, pushing as much snow as I could in front of me. It all went through and under the thin iron railing and cascaded down onto him, about 15-18 linear feet of snowfall the width of the shovel came down on his head and there wasn't a thing he could do about it with that snowblower.
