First off - never let the wife watch (especially film). Prospective girlfriends, other guy's wives, or any other woman you want to bed, fine, but never your own wife. It's a curse from the Gods.
Second - destroy the whole house, not part of it. Your deductible will kill any fun you might have had with the insurance money on a claim that small.
Third, your saw looked (and sounded) a bit small for the job. A proper sized saw for the job allows better control of your cuts.
Fourth - hard to tell from the video, but your notch looked too deep. You lose a lot of control over the drop that way.
Fifth - hire pros.
Sixth - you have snow?
Seventh - sell your saws and buy beer.
Eighth - how come you wife sounds like my grandmother? Is your wife my grandmother? Grampa, is that you?
