There is a good way, a cool way, and a completely wrong way to clear snow from a roof, and I will tell you about the latter.
This hilarious video was posted on YouTube yesterday, and hasn't really received a lot of views, which I believe are definitely deserved.
It is appropriately titled “The wrong way to clear snow from a roof,” and covers exactly that. A man starts shoveling snow from the rooftop of his home, while another films him, as if knowing what was about to happen.
He tumbles off the roof, but thankfully lands on a cushy layer of snow. He seems not to take it too seriously, so I can assume he is not hurt, although his ego took the biggest fall.
