What have been the worst (serious or humorous) handyman or handywoman
accidents that you've experienced so far (or someone you know, or saw
it happen to, got to experience) and please elaborate on what
unfortunately went wrong.

My dad was a contractor for decades. He did mostly fairly large projects
such as home additions, and that sort of thing. Some of his projects
were even featured in national magazines, so he had a great reputation.

When business got slow, my dad would accept smaller projects. I used to
help my dad out on jobs for many years.

On one job that consisted of adding a deck onto a kitchen in a modest
row house, my dad had to remove a window air conditioner in order to
knock down the kitchen's exterior wall.

My dad declined my offer to help and he said it was just a light air
conditioner and he could handle it himself. He opened the window to
release the air conditioner and it dropped out to the ground below. The
man who owned the home and I were both watching as this happened and the
look on my dad's face was priceless.

As it happened, the customer was behind in paying my dad, but my dad
liked the guy so he didn't make a big deal of it. After the crashing
sound ended, my dad just said in a smug face to the customer that he
could deduct the price of a new AC off the money he owed my dad.

Fortunately, the customer was nice about the situation, but the look on
his and my dad's faces just cracked me up. I was literarily on the floor
laughing! The look on my dad's face as he snarled at me to stop laughing
only made me laugh more.
